Anything that is spreading worldwide and fast is prone to mutations. This is because as it hit different people causing many infections the outcome is not always predictable and it’s different. The more they spread the more opportunity there is to replicate to something else. All the approved vaccines are designed to fight against the virus and its current mutations. The most delta variant is much stronger and is causing severe illness compared to before but the measure to protect against the variant still applies. The vaccines are working well and there have been no reasons to doubt the vaccine. (Mahase E, 2021).
The available vaccines worldwide include the Pfizer -BioNTech or Moderna which is being administered in two doses with a difference of two months and the Johnson & Johnson’s J&J vaccine which is a single dose (Livingston E, 2021). It takes roughly about 2 weeks after complete vaccination for the body to build protection toward the vaccine. With full vaccination is highly advisable to keep of lard crowds or maintain social distance since there are possible infections of the covid 19 virus.
The breakthrough infections are there but still very minimal. These are the infections that are recorded from people who are already vaccinated. The symptoms are less severe and there are fewer complications. There are no 100% effective vaccines and thus these infections are to be expected. The positive side is that people are strong to fight the virus with less hospitalization.
Even with the new variant, the vaccines have not had any complaints of not working. They are effective as before. To ensure that people are fully protected against the Delta variant it’s still advisable to wear a mask when in public even if vaccinated. It’s also advisable to avoid areas of high transmissions since there is no evidence of what might happen in case of a new variant.
