Sinovac’s Risk of Causing Bell’s Palsy?

Bell's Palsy

A study published in The Lancet Infectious Diseases showed that Bell’s palsy increases after the first dose of Sinovac’s Covid-19 vaccine. However, the level of protection from Covid-19 infection is greater. In addition to Sinovac, the risk of developing Bell’s Palsy also arises after the use of the Pfizer vaccine. 

Quoted from, in a study conducted on more than 451,000 people, there were 28 cases of facial paralysis or bell’s palsy after the Sinovac vaccine. This figure is higher than the Pfizer-BioNTech vaccine, which was 16 cases.

The Hong Kong study assessed the risk of adverse events occurring after 42 days of vaccination. However, Sinovac has not made a statement on the findings.

While the side effects of injecting the vaccine made by Pfizer-BioNTech found 13 people experiencing facial paralysis in Israel. However, facial paralysis is included in the mild category and is easily cured.
