Vaccination is the main factor that doctors and medical experts have long emphasized to reduce the risk of corona, especially at a critical timeline like this when we also face additional concerns about potential new waves of the corona virus.
Vaccination is also considered a passage for people to resume their normal “mask-free” lives to roam freely without fear of contracting the disease, and many have a question about the possibility of transmitting infection from vaccinated people to others.
The importance of receiving the vaccine
According to timesofindia, all currently approved COVID-19 vaccines have been well studied and have good potential for protection, which means they may strengthen the body’s immune response to the virus and reduce the risk of complications, including hospitalization.
Likewise, vaccines must also reduce transmission rates – the way infection spreads from person to person, however, there is little substantiated evidence to support the claim so far.
This may indicate that while vaccines are effective against diseases with poor symptoms and outcomes, the risks of transmission remain worrisome. Until such time as we do not gather sufficient evidence, it would be safe to assume that vaccination does not automatically reduce transmission either, and thus, may A vaccinated person is at risk of spreading the coronavirus to others.
Low transmission rates depend on the vaccine
Even with the little evidence available that vaccines may reduce transmission to some extent (not completely), much depends on how well the vaccine prevents infection.
Different vaccines work differently, some have been shown, for example, to reduce moderate and severe infections with the coronavirus, so people who get superinfected only get the mild COVID-19 virus, while others work to prevent infection completely, so , a lot of the risk factors, whether or not you get COVID-19 or infect others, also depends on which vaccine you have, and it works reliably, and real-world data backing it up.
Some experts also believe that transmission of COVID-19 after vaccination also depends on asymptomatic spread – which many vaccines have not yet considered.
Virus transmission without symptoms
In terms of how SARS-COV-2 spreads, asymptomatic transmission of the virus makes things more complicated. Not only is it a relatively new virus, but COVID-19 also presents special challenges because the infection can be spread by both asymptomatic carriers. As well as non-carriers, this means that a person who is asymptomatic and does not get tested may silently spread the disease to others, a scenario that could very well happen with vaccinated recipients as well.
Clinical studies conducted over the past year indicated that the majority of COVID infections were caused by asymptomatic people or those with mild, barely noticeable symptoms, i.e. those who were not suspected of having COVID and may also have not been diagnosed.
This could be the case with some vaccinated recipients, who may contract COVID-19, not develop symptoms, yet unknowingly spread the infection to others.
Variants may make vaccines less effective
The third wave of coronavirus in many countries has been driven by a growing wave of fears, which are not only highly contagious and spread easily but also have the ability to bypass antibodies.
This is also another possible scenario where vaccinated people may spread the virus to others, when infected, while people may be less likely to develop serious illness, or develop fewer symptoms, the easy transmission of the mutations can increase the chances of infection for those at risk. .
-Who is in danger now?
Anyone who is currently unable to be vaccinated, or who may not be eligible for the vaccination, is most likely to contract the disease and suffer worse outcomes.
This means that people with medical or chronic conditions, a weakened immune system or disease that prevents them from being vaccinated, and children under 18 who have not been willingly vaccinated all carry an equal risk of infection.
