A new study shows that even if you are already infected with the Corona virus, you can still benefit from a vaccine that can help prevent further infection, according to the “Health” website.
The researchers found that Danish patients had between 60% and 94% protection from reinfection, depending on the changing wave of Corona.
According to the study, which was published in the journal PLOS Medicine, Katrin Windrup Nielsen, study author and researcher at the Serum Statens Institute in Denmark, said: “In our study, we found a great efficacy of the vaccine against reinfection with corona, and this demonstrates the importance of vaccination also for those who may be protected with natural immunity.” “.
The team of researchers analyzed infection and vaccination data from Danish registries that included all people living in Denmark who tested positive for the virus or were vaccinated between January 2020 and January 2022.
This included more than 200,000 people who tested positive during the alpha, delta and omicron waves.
The researchers found that vaccination provided up to 71% protection against reinfection during the alpha variable period for Corona, provided 94% protection during the delta period. By the Omicron period, that protection had decreased to about 60%. The additional protection lasted up to nine months.
The researchers said this insight into the vaccine’s efficacy may help plan future vaccination strategies. The study was too short to determine whether the vaccine protects against severe outcomes, such as death and hospitalization.
