A drop-off in antibody levels after a second dose of the vaccine has informed the recommendation of a third booster shot for over-50s and younger adults with health conditions in the UK. Invitations to book the third coronavirus vaccine will today be sent out to more than a million Britons in a bid to "Strengthen the wall of defence" against COVID-19 created by the vaccine.
In new data submitted to the Food and Drug Administrations [FDA], Pfizer has outlined the different side effects to expect from a third dose of their vaccine.
Data submitted to the Food and Drug Administrations [FDA] shows that the side effects after the second dose of vaccine are more likely to affect younger people.
Experts studying 306 booster recipients found that 44 of them developed an unexpected side effect, reported Texas Breaking.
The most unexpected side effect observed was the swelling of lymph nodes, which appeared in 16 of the 306 participants.
When researchers compared these side effects with those of second-dose recipients, they noted the booster shot's side effects were similar.
Pfizer's application to administer a third dose of its vaccine to people 16 and across the US was voted against by an advisory committee for the FDA. Committee members on the advisory panel for the FDA expressed scepticism that Pfizer had provided adequate data supporting the need for the boosters in the general population in the US. The panel argued that there wasn't enough data on the safety of booster shots among younger people, who are more susceptible to side effects from the vaccines such as myocarditis.
