Evidence for a 10-year TBE vaccine booster interval: an evaluation of current data

Review

作者: Torgler, Ralph ; Schelling, Jörg ; Einmahl, Suzanne ; Larsen, Carsten Schade

INTRODUCTION:

Tick-borne encephalitis (TBE) is rapidly spreading to new areas in many parts of Europe. While vaccination remains the most effective method of protection against the disease, vaccine uptake is low in many endemic countries.

AREAS COVERED:

We conducted a literature search of the MEDLINE database to identify articles published from 2018 to 2023 that evaluated the immunogenicity and effectiveness of TBE vaccines, particularly Encepur, when booster doses were administered up to 10 years apart. We searched PubMed with the MeSH terms 'Encephalitis, Tick-Borne/prevention and control' and 'Vaccination' for articles published in the English language.

EXPERT OPINION:

Long-term immunogenicity data for Encepur and real-world data on vaccine effectiveness and breakthrough infections following the two European TBE vaccines, Encepur and FSME-Immun, have shown that extending the booster interval from 3-5 years to 10 years does not negatively impact protection against TBE, regardless of age. Such extension not only streamlines the vaccination schedules but may also increase vaccine uptake and compliance among those living in endemic regions.

Abstract:

Background:

The purpose of this exploratory study was to evaluate different accelerated tick-borne encephalitis (TBE) vaccine schedules for last-minute travellers.

Methods:

In a single-centre, open-label pilot study, 77 TBE-naïve Belgian soldiers were randomized to one of the following five schedules with FSME-Immun®: group 1 (‘classical accelerated’ schedule) received one intramuscular (IM) dose at Day 0 and Day 14, group 2 two IM doses at Day 0, group 3 two intradermal (ID) doses at Day 0, group 4 two ID doses at Day 0 and Day 7 and group 5 two ID doses at Day 0 and Day 14. The last dose(s) of the primary vaccination scheme were given after 1 year: IM (1 dose) or ID (2 doses). TBE virus neutralizing antibodies were measured in a plaque reduction neutralization test (PRNT90 and 50) at Days 0, 14, 21, 28, Months 3, 6, 12 and 12+21 days. Seropositivity was defined as neutralizing antibody titres ≥10.

Results:

The median age was 19–19.5 years in each group.Median time to seropositivity up to Day 28 was shortest for PRNT90 in ID-group 4 and for PRNT50 in all ID groups. Seroconversion until Day 28 peaked highest for PRNT90 in ID-group 4 (79%) and for PRNT50 in ID-groups 4 and 5 (both 100%). Seropositivity after the last vaccination after 12 months was high in all groups. Previous yellow fever vaccination was reported in 16% and associated with lower geometric mean titres of TBE-specific antibodies at all-time points.The vaccine was generally well tolerated. However, mild to moderate local reactions occurred in 73–100% of ID compared with 0–38% of IM vaccinations, and persistent discolouration was observed in nine ID vaccinated individuals.

Conclusion:

The accelerated two-visit ID schedules might offer a better immunological alternative to the recommended classical accelerated IM schedule, but an aluminium-free vaccine would be preferable.

Effectiveness of Vaccination Against Tick-Borne Encephalitis in the Czech Republic, 2018−2022

Article

作者: Bender, Cody ; Pilz, Andreas ; Erber, Wilhelm ; Edwards, Juanita ; Maly, Marek ; Madhava, Harish ; Krivohlavkova, Dagmar ; Zhang, Pingping ; Vlckova, Iva ; Angulo, Frederick J. ; Moïsi, Jennifer C. ; Harper, Lisa R. ; Kyncl, Jan ; Orlikova, Hana

Background: Tick-borne encephalitis (TBE) is caused by the tick-borne encephalitis virus (TBEV). TBEV infection can cause symptoms of central nervous system (CNS) inflammation and result in severe consequences including death. TBE is an increasing health threat in the Czech Republic and elsewhere in Europe. In 2020, 23% of 3734 TBE cases reported to the European Centre for Disease Prevention and Control were from the Czech Republic. TBE vaccination is universally recommended in the Czech Republic, but a full analysis of TBE vaccine effectiveness (VE) in the Czech Republic has not been published. Methods: TBE is a notifiable disease in the Czech Republic with mandatory reporting of cases (i.e., laboratory-confirmed TBEV infected patient with symptoms of CNS inflammation) and vaccination history to public health authorities. TBE VE was estimated using the screening method utilizing public health surveillance data from 2018 to 2022 and online household surveys of the general population on TBE vaccine uptake conducted in 2019-2022. Results: In 2018-2022, 3648 TBE cases were reported in the Czech Republic; 98.1% (3105/3166) of TBE cases with known vaccination history were unvaccinated. Among 42,671 persons surveyed from the general population who had known TBE vaccination history, 66.5% were unvaccinated. VE against TBE was 97.6% (95% confidence interval 95.7-98.7). When stratified by age group, VE was 97.1% (88.4-99.3) in 1-15 years of age, 97.9% (95.3-99.0) in 16-59 years of age, and 96.9% (90.5-99.0) in ≥60 years of age. TBE vaccination averted an estimated 1020 TBE cases in the Czech Republic from 2018 to 2022. Conclusions: This first published study with a full analysis of TBE VE in the Czech Republic showed that vaccination was highly effective for the prevention of TBE including in children, an age group with increasing TBE disease burden. Vaccination averted hundreds of TBE cases and hospitalizations despite the relatively low compliance with TBE vaccine recommendations. To prevent additional TBE cases in the Czech Republic, enhanced efforts to increase TBE vaccine uptake are needed.

Pfizer, US Army nab a new approval for a decades-old vaccine

It won’t make Pfizer even a minuscule fraction of what its other new vaccines have and will earn, but the New York drugmaker has gotten yet another inoculation approved by the FDA. Pfizer announced Monday that US regulators have OK’d Ticovac, the company’s vaccine for tick-borne encephalitis, a virus that infects the brain and nervous system and can sometimes cause long-term cognitive, skeletal or muscular effects. If you’ve never heard of tick-borne encephalitis, that’s likely because it essentially does not exist in the United States. From 2000 to 2017, the CDC recorded eight cases in the US, all from travelers who had spent time in China or Europe, where Ticovac has been approved since the 1970s. (China has its own home-grown vaccine, called SenTaiBao, as does Russia). The US approval comes after a years-long collaboration between Pfizer, which picked up the shot when it bought out Baxter’s vaccine unit for $635 million in 2014, and the US Army. Military service members stationed abroad make up the vast majority of US residents who receive Ticovac, but doing so can be cumbersome: It requires three different shots and the military member often needs to obtain clearance to leave base and travel to a different country for each of them. The US approval will hopefully mean that military members can receive doses while still in the US. Unlike its Covid-19 shot or the recently approved Prevnar 20 shot, the TicoVac OK won’t mean much for Pfizer’s bottom line: Last year, the company collected just $27 million from TicoVac sales. But it will help provide strong protection against the tick-borne virus: Estimates of TicoVac’s efficacy vary but tend to hover between 96% and 99%, about the best researchers can hope for in a vaccine. In an era of mRNA, it’s a reminder of just how effective old-fashioned technology can be. TicoVac is made from an inactivated virus, the same platform Jonas Salk used for polio. The approval also comes as tick-borne encephalitis becomes a broader issue. The CDC estimates that the virus has expanded its range over the last three years, likely due to a complex combination of causes, including both changes in climate and changes in how researchers diagnose and conduct surveillance.

FDA Gives Nod to Pfizer’s Tick-Borne Encephalitis Vaccine

This approval makes TICOVAC the only FDA-backed vaccine in the U.S. to protect people of all ages against the virus when visiting or living in TBE endemic regions. The U.S. Food and Drug Administration (FDA) has approved Pfizer’s tick-borne encephalitis (TBE) vaccine TICOVAC to prevent TBE in people aged 1 year and older. This approval makes TICOVAC the only FDA-backed vaccine in the U.S. to protect people of all ages against the virus when visiting or living in TBE endemic regions. TBE, a viral infection, is transmitted to humans via an insect bite. The infection, which affects the brain and spine, has been reported in over 35 countries across Asia and Europe but is not known to be endemic in the states. Recommendations from the European Centre for Disease Prevention and Control (ECDC) state that people who live or are traveling to endemic regions should receive TBE vaccination. Currently, experience with Pfizer’s TBE vaccine has been documented outside the U.S. for more than 45 years. Additionally, more than 170 million vaccine doses have been delivered to people since 1976. “We are proud to deliver the first vaccine to help protect people in the U.S. against TBE, if they are traveling to any risk areas,” said Pfizer’s global president of Vaccines, Nanette Cocero, Ph.D., in a statement . “This vaccine has helped to protect millions of people in TBE endemic regions since its first approval outside the U.S. 45 years ago. This authorization helps to ensure that people from the U.S. are also able to receive this vaccination if needed, reflecting our commitment to provide health for all.” The vaccine is marketed in Europe as FSME-Immun and TicoVac and in the U.S. as TICOVAC. The company says the vaccine was developed with “a master ‘seed’ virus that is similar to the TBE virus found in nature” and is capable of inducing “neutralizing antibodies against the natural TBE virus.” Clinical trials have assessed the safety and immunogenicity of the Pfizer TBE vaccine across patients aged 1 to 15 years as well as patients older than 16. Seropositivity rates after three doses were 99.5% in patients between 1 and 15 years and 98.7% to 100% in people older than 15 years. These studies also found TICOVAC was generally well-tolerated and corresponded with no unexpected side effects or serious adverse events related to the vaccine. Pfizer said after the FDA approval that the U.S. Centers for Disease Control and Prevention’s (CDC) Advisory Committee on Immunization Practices (ACIP) will soon discuss recommendations on the appropriate use of TICOVAC based on the available clinical evidence. On Thursday, the FDA also gave the amended Emergency Use Authorization for Pfizer and BioNTech’s COVID-19 vaccine, which allows a third booster shot for patients who are immunocompromised. The amendment specifically targets patients who have been diagnosed with illnesses considered “equivalent” to immunocompromising conditions as well as those who have received a solid organ transplant. News of the amendment arrive in the midst of rising cases attributable to the Delta variant. The CDC is also set to discuss additional recommendations for COVID-19 vaccine boosters in immunocompromised patients. These recommendations are expected sometime today. Amendments made to Pfizer and Moderna’s COVID-19 vaccine administration schedules were made after the FDA reviewed data that showed a booster shot, administered six months following the second dose, could offer increased protection for the immunocompromised. Additionally, the FDA states that people who are in close physical contact with these patients should also receive a booster shot. Featured Jobs on BioSpace
