Everything You Need To Know About The Third Vaccine (Booster Shot)
COVID-19 vaccination rollout started in early 2021, and as the year enters its fourth quarter, many countries seek to offer a third dose or a booster shot to fully vaccinated individuals. The human body needs added protection, particularly with virus strains or diseases that might mutate over time.
It is common knowledge that vaccines may wane in efficacy after a certain period. While antibodies receive a boost from vaccines to better fight against the disease, they gradually drop as time passes. Much like any other vaccines, COVID-19 jabs may also require another dose to increase antibody levels once more. The goal with booster shots is to gain longer-lasting protective immunity against the novel coronavirus.
Once an individual receives a third dose of the COVID-19 vaccine, they may experience the same side effects of the first two doses. They should keep in mind, though, that if symptoms persist for longer than usual, it might be an indication of a coronavirus infection or another infection. In such cases, they must take either an RT-PCR test or a rapid antigen test to determine their current health status.
With more individuals receiving their complete vaccination and with the third dose on its way, countries have started lessening the restrictions implemented during the pandemic. For instance, the UK government recently announced that they are lifting self-quarantine requirements for fully vaccinated individuals entering the UK. Officials are also looking into the possibility of changing the protocols for physical distancing and the wearing of face masks.
However, mandates like the fit to fly COVID test or coronavirus testing for other endeavours will remain. For travellers are heading abroad, they should first verify if the country they are going to requires a specific type of COVID test or if they accept rapid antigen test for travel.
