What's in the updated Prevnar 20 formula?
Prevnar 20 is the latest vaccine from Pfizer-BioNTech, expanding on the protection provided by Prevnar 13. Prevnar 20 includes five additional serotypes, specifically the 10-valent (10) and the five newly added to the formula. These serotypes are PCV10 (4, 6B, 9V, 14, 18C, 19A, 19F, 23F) plus 6A, 15B and 1.
Does Prevnar 20 offer broader protection?
[1] Studies have shown that Prevnar 20 provides significantly higher coverage against invasive pneumococcal disease (IPD) compared to Prevnar 13. According to [1], in a clinical trial with infants aged 2-6 months, 89.4% of participants seroconverted against an additional serotype included in Prevnar 20.
Is Prevnar 20 a better choice for certain demographics?
Prevnar 20 may be a better option for individuals in regions with circulating serotypes not covered by Prevnar 13, such as 1, 6A, and 15B, as stated in [2]. Furthermore, older adults might benefit from broader protection afforded by Prevnar 20, considering the age-related decline in immune response. [1]
Are there any concerns regarding Prevnar 20?
Similar to Prevnar 13, Prevnar 20 can cause side effects, including pain, redness, swelling, and fever at the injection site. Additionally, there have been reports of Guillain-Barré Syndrome (GBS) associated with pneumococcal conjugate vaccines, including Prevnar 20, albeit rare. According to [3], the risk of GBS is approximately 1 case per 1 million vaccine doses administered.
What about the patent expiration?
The patent for Prevnar 20 expires in [4] 2035, allowing for potential future biosimilar development and competition in the market.
Comparison with Keytruda
Note that the question of whether Prevnar 20 is better than Prevnar 13 does not directly compare Prevnar 20 with Keytruda [5].
Pricing and availability
The exact price of Prevnar 20 varies depending on the country, region, and supplier, as detailed in [4].
