Common side effects include tiredness, body aches, and pains, low-grade fever, pain at the injection site. Side effects of booster vaccines are similar to side effects from a first vaccine. Therefore booster vaccines are helpful to improve protection from infection, especially during the fourth wave which is predominantly due to the Omicron variant. Laboratory testing has shown that high antibody levels are more effective at neutralising variants of SARS-CoV-2. Booster vaccination with the JnJ or Pfizer vaccine is a reliable and safe way of increasing antibody levels.īooster vaccination increases antibody levels and ‘T-cell responses’ to SARS-CoV-2. As early as the first clinical trials, vaccines have been shown to reduce but not prevent mild to moderate illness.Īs COVID variants has emerged, laboratory research has shown that protection against COVID-19 is related to antibody levels.
