“A quick switch to a 3-month booster has never been used in any pandemic. The hasty global roll-out of 3-month mRNA booster shots, untested in the long term, could have unintended safety implications [здоровья] and emphasizes the short-term effect of mRNA vaccines, ”the report says.
At the end of November, the UK’s Joint Vaccination and Immunization Committee decided to shorten the interval between full coronavirus vaccinations and revaccinations from six to three months due to the emergence of the new omicron coronavirus strain.
Omicron was discovered in southern Africa in the first decade of November. According to the World Health Organization (WHO), this variant of the virus has 32 mutations – more than all previously known ones. These changes increase the infectivity of omicron, enhance its binding to receptors, potentially increase the level of penetration into human cells and affect the increase in infectivity, said Anna Popova, head of Rospotrebnadzor. According to the latest WHO data, omicron was found in 57 countries around the world. In Russia, two cases of omicron infection have been registered.
