British experts have predicted that vaccination against COVID-19 will be maintained “for years to come.” About it it says in a report by the UK Government Emergency Advisers Group (SAGE).
The vaccine-induced immunity to the coronavirus and the potentially severe disease is likely to wane over time, according to the document. Therefore, the experts concluded that the population may require revaccination. They also said that vaccination campaigns may be ongoing for many years.
It is noted that experts are not sure how often citizens will need to be vaccinated against COVID-19. In their opinion, most likely, over time, it is the effectiveness of vaccines against infections and a mild course of the disease that will decrease, but they will still be effective against a severe form of the disease.
Earlier, experts noticed that reinfection with coronavirus is characterized by a lower viral load compared to the first infection, which leads to weaker symptoms. This could indicate that COVID-19 may turn into a relatively mild respiratory illness. According to a survey conducted by the Office for National Statistics (ONS) in the UK, of the 19,470 people who have recovered from the coronavirus, 195 people were re-infected. However, only in 48 cases the viral load was high.
