joint pain for 22% of participants, including severe cases for 2.44%Ī smaller trial including 15,187 participants in the UK found similar results.nausea and vomiting for 11% of participants, including severe cases for 0.23%.fever for 6% of participants, including severe cases for 0.37%.Less common side effects after the second dose included: pain upon and after vaccination for 60% of participants.tenderness at the injection site for 73% of participants.While side effects occurred after the first dose, they were more common after the second dose. They also tracked side effects for 7 days after each dose. Overall, the researchers found that the Novavax vaccine was 92.6% effective against the Alpha and Beta variants of the virus. On a ratio of 2:1, they received two doses of either the Novavax vaccine or a placebo. One trial in the United States and Mexico included 29,949 participants ages 18 and over who had not previously contracted SARS-CoV-2. In April 2021, a Chinese official called Gao Fu said that the country’s COVID-19 vaccines “do not achieve very high protection rates.” Gao, head of the Chinese Center for Disease Control and Prevention, later claimed that people had misinterpreted his comments.The results from two large phase 3 trials on Novavax have been published. Some individuals have also aired concerns over the vaccine’s efficacy. Taiwan News reported that censors took Tao’s post down in early January and that 2 days later, Tao retracted his criticism, saying that it was a joke.

The manual listed the vaccine’s 73 local and systemic side effects, leading Tao to describe the vaccine as the “most unsafe vaccine in the world.” However, the number of side effects that the manual lists is not, in itself, an indication of the vaccine’s safety. There is still some controversy surrounding the vaccine, which a lack of detailed safety and efficacy data and the early rollout of the vaccine have fueled.Ī January 2021 news article reported that Shanghai-based vaccine expert Tao Lina had uploaded a digital version of the vaccine’s manual to the web. However, the WHO highlights a gap in BBIBP-CorV’s evidence base for older adults. There were no reported serious adverse events for this age group. Safety data from 1.1 million Sinopharm vaccine doses that older adults - aged 65 years and over - received in China list the most common side effects as dizziness, headaches, fatigue, nausea, fever, vomiting, and allergic dermatitis. Although there were 11 reported cases of facial nerve symptoms, assessors concluded that these were unrelated to the vaccine. There were also 202 cases of fever, including 86 classed as severe. These side effects included local reactions of redness and swelling at the vaccination site.

Among the 5.9 million people who had received the vaccine in China by December 30, 2020, there were 1,453 reported adverse events.

The WHO also considered post-authorization data in the form of safety data gathered during China’s rollout of the vaccine. There was also one diagnosis of thrombus (blood clot) in the vaccine group. The WHO identified two serious adverse events that were possibly linked to the vaccine - serious nausea and a rare neurological disorder known as acute disseminated encephalomyelitis.
