SARS-CoV-2 is the virus that causes coronavirus disease 2019 (COVID-19). Some have been stated, to be of particular importance due to their potential for increased transmissibility, [1] increased virulence, or reduced effectiveness of vaccines against them. [2] [3] These variants contribute to the continuation of the COVID-19 pandemic.
“Since the strain only circulated for a few months at the beginning of 2021, we don’t have a lot of information about vaccine prevention. It had been outcompeted by the time the vaccines ...

While mRNA vaccines, such as the Pfizer–BioNTech COVID-19 vaccine and Moderna COVID-19 vaccine showed higher efficacy of +90%, mRNA vaccines present distribution challenges for some nations, as some may require deep-freeze facilities and trucks. By contrast, the BIBP vaccine can be transported and stored at normal refrigeration temperatures. [17]
Virus experts say it’s unclear if new strains pose any concern for vaccines or cause more severe disease.
