The World Health Organization has announced recommendations on vaccinations due to the new strain of the corona virus. The new version of Covid-19, PJ.2.1, may differ from other variants in causing severe sore throats and longer periods of energy loss after illness. Despite the high rate of spread, there are no clinical data indicating a more severe course of the disease compared to other variants of SARS-CoV-2. Experts note that PJ.2.1 does not show an increase in the number of pneumonia, respiratory failure or deaths. The main risk group is the elderly aged 60 and over. WHO will review data on versions PJ.2.1, ST.1 and SW.2.1 during discussions in December. Experts will evaluate the genetic evolution and spread of variants, their antigenic characteristics and data on the immunogenicity and efficacy of vaccines. Read the newspaper. Ru» ב-MAX.
