According to Moderna, Mardner's bivalent COVID-19 vaccine can effectively fight against the original strain in COVID-19 and the mutant strain in Omicron, COVID-19. Clinical trial data show that Madena's bivalent COVID-19 vaccine can effectively fight against Covid-19's variant strain of Omicrovirus BA. 1 strain, against Covid-19's original strain, and against Covid-19's currently rampant variant strains of Omicrovirus BA.4 and BA.5.
Starting from the out-of-control COVID-19 epidemic in Britain, it is precisely because of the severe COVID-19 epidemic in Britain that this country approved Madena bivalent COVID-19 vaccine, becoming the first country in the world to approve this vaccine. Judging from the current development of mutant strains in COVID-19, these four main variants, namely, α mutation α, β mutation β, δ mutation δ and Omicron mutation Omicron, are considered to be widespread, and they have all been popular in Britain, among which α mutation α was first discovered in Britain.
? We can only say that these approved COVID-19 vaccines, no matter how resistant they are to the strains, should not relax their daily epidemic prevention. It is precisely because of these countries? Lie flat? Response, leading to waves of ups and downs of COVID-19 epidemic around the world, leading to repeated mutations in COVID-19.
