write an article on importance of covid19 vaccination
Answers
Answer:
Currently, a total of seven COVID-19 vaccines available across three platforms have been approved and are being rolled out across the globe. However, some question the efficacy of these vaccines, especially given the emergence of new strains of the virus. Vaccines must be effective at significantly reducing the spread of the virus for them to be successful.
Research has demonstrated that the Moderna and the mRNA-based Pfizer vaccines are 94-95% effective, and these figures have proven true even in trials studying those at high risk and the elderly.
It is a common misconception that this means 95% who get the vaccine are protected from the disease, leaving 5% unprotected. If this were true, in a population of 100,000 were vaccinated this would lead to 5,000 people contracting the virus and developing the disease over three months. This rate is similar to the current UK COVID-19 case rate.
The 95% effectiveness actually means that people with the vaccine have a 95% lower risk of COVID-19 when compared to a control group. Without the vaccine, we would expect roughly 1% of the population to get the disease, and with the vaccine, this reduces to 0.05%. At such low rates, the vaccines will allow society to get back to ‘normal’ and for restrictions to be permanently eased.
