![]() ![]() It was equally effective in people over the age of 65 years, as well as people with some stable pre-existing medical conditions. People who had 2 doses of Pfizer were about 95% less likely to get ill from COVID-19 than people who did not get the vaccine. The benefits of vaccination with Pfizer greatly outweigh the risk of side effects.Ī very large clinical trial showed that Pfizer is effective in preventing and protecting against serious illness from COVID-19 in people aged 12 years and older. You can read the full Comirnaty (Pfizer) Consumer Medicine Information document on the TGA site for more details (click 'I accept' to see the PDF). This video from John Hopkins Bloomberg School of Public Health explains how mRNA vaccines work. Pfizer does not contain any live virus and it cannot give you COVID-19. Your immune system cells then recognise the spike protein as a threat and begin building an immune response against it. The RNA from the vaccine does not change your DNA in any way, and your body quickly breaks it down. This type of vaccine uses a genetic code called RNA to make your body's cells produce the coronavirus’ specific spike protein. Pfizer is a messenger RNA (mRNA) vaccine. Vaccinating children can help protect children from getting seriously ill or dying from COVID-19.įind out more information on COVID-19 vaccines and children. The Therapeutic Goods Administration (TGA) has provisionally approved the Comirnaty (Pfizer) vaccine for children aged 5 years and over. Read the latest advice and recommendations for booster doses. The booster dose is given 6 months or more after the last dose or COVID-19 infection, whichever is more recent. Pfizer can also be used as a booster dose in people aged 5 years and older. It is usually given 8 weeks after the second dose of the primary course. ![]() You may not be fully protected against COVID-19 until 7 to 14 days after your second dose. Some people who are severely immunocompromised are recommended to have a third dose as part of their primary course. Pfizer can be used for this third dose. A shorter interval may be recommended for people at higher risk of severe COVID-19 (including older adults and people with underlying medical conditions), or before international travel. It is preferable to have the first 2 doses 8 weeks apart, but the dose interval between doses can be reduced to 3 weeks. Dose schedule Primary courseįor most people the Pfizer primary course is 2 doses, 8 weeks apart.įor children aged 6 months to under 5 years, the primary course is 3 doses, 8 weeks apart. However, both the bivalent and original vaccines provide significant protection from severe disease against Omicron subvariant infections. The Pfizer bivalent COVID-19 vaccine targets the original 2020 strain and the Omicron variant BA.1.Ĭompared to the original vaccines, ATAGI found it triggers a modest improvement in the immune response against both strains. The Australian Technical Advisory Group on Immunisation (ATAGI) has provided a recommendation that the Pfizer bivalent vaccine can be used as an alternative vaccine for any booster dose in people aged 18 years or older, according to the current ATAGI recommendations for booster doses. On 28 October, the TGA provisionally approved Pfizer’s bivalent COVID-19 vaccine for use as a booster dose in adults 18 years and over.
