Can COVID-19 Vaccination Also Stop Transmission of Virus?
Since the COVID-19 Vaccination has begun across the world, many scientists have been doing their research on various factors of the vaccine, including vaccination can reduce the transmission of the virus.
The primary focus of vaccines is to boost immunity and prevent a person from developing high risks due to infection. However, it is clear that the vaccine is highly effective in preventing a person from higher risks.
Researchers believe that vaccines develop optimum amounts of neutralizing antibodies in the body that not only bind the virus but also prevent it from infecting. Scientists are also still figuring out the durability of the immunity of the COVID-19 Vaccination. Can a vaccinated person spread coronavirus? Immunologists believe that vaccines protect against viral illness and also reduce the transmission of the virus. COVID-19 creates a challenge because people with asymptomatic and pre-symptomatic infections can spread the disease.
Some scientists estimated that the number of asymptomatic COVID-19 infections in the overall population could be 3 to 20 times higher than the number of confirmed cases. Research suggests that the undocumented were, either asymptomatic or experienced mild symptoms, responsible for up to 86% of infection spread.
The CDC tested volunteer health care personnel and other front-line workers at different US locations weekly for three months. The research found that participants who were vaccinated were 25 times less likely to test positive for Coronavirus than those who were not vaccinated.
Studies like this clear that vaccinated people are less likely to get infected and also spread the virus. Without contact tracing to track transmission in a large population, it is impossible to know whether the assumptions are true.
But what we know from the research is that if someone gets infected even after COVID-19 vaccination, symptoms will be milder and risks such as breathlessness and severe lung infections are lower. A preprint study, which has not been peer-reviewed, suggests that the mRNA Covid-19 vaccine can produce antibodies in the oral and nasal fluid to help fight against coronavirus. The route from where it enters the body, antibodies in the mouth and nose block the virus and stop it from getting into the body.
This would mean that vaccinated people probably wouldn’t spread the virus through respiratory droplets. These few pieces of evidence are promising. But without more studies, scientists cannot conclude that Vaccines really do protect against Virus transmissions.
