Nearly a year after the COVID-19 pandemic began, several vaccines have now been rolled out across the world, including some that use new RNA technology that has never been approved for use on humans before. Concerns now arise on weather the developed covid 19 vaccines are effective on the new variants of the virus amid mass vaccinations worldwide. The deadly virus (SARS-CoV-2) that causes coronavirus disease 2019 (COVID-19) just like other viruses constantly change through mutation. When a virus has one or more new mutations it’s called a variant of the original virus. Currently, several variants of the virus (SARS-CoV-2) that causes coronavirus disease 2019 (COVID-19) are creating concern in various parts of the world.
According to research, the new variants are more contagious and might cause more severe illness. The greatest risk of transmission is among unvaccinated people. Studies have shown that a known as Delta (B.1.617.2). might reduce the effectiveness of some monoclonal antibody treatments and the antibodies generated by a COVID-19 vaccine. Another variant called Gamma (P.1). also reduces the effectiveness of some monoclonal antibody medications and the antibodies generated by a previous COVID-19 infection or a COVID-19 vaccine.
While research suggests that COVID-19 vaccines are slightly less effective against the variants, the vaccines still appear to provide protection against severe COVID-19. Early research from the U.K. , Canada and U.S suggests that Pfizer-BioNTech COVID-19 vaccine, the Moderna COVID-19 vaccine and Janssen/Johnson & Johnson COVID-19 vaccine are all effective at preventing symptomatic COVID-19 virus caused by the new variants.
