While getting vaccinated gives people considerable insurance against falling ill with Covid, which is sometimes fatal, if they can still get silently infected with SARS-CoV-2, they might pass it on, potentially sickening people who aren't immune.

Hi

immunity is a tricky issje and is subjected to wide and variable range of diversities not only in COVID 19 era but in other disease

most patient will develop IgG Ab in 2 to 3 Weeks still some showed delayed respoce and still expressing IgM Ab

Suggesting that their immuns system has not fully concord the pathogen

A freind of mine took 10 days off fallowing the infection her symptom were exagurated fallowing her sickleave ends

she progressed rapidly into ICU for respiratory support

see this diversity in reacting to the infection highly suggest a gentic or other patient related variable

They may act as carriers

This issue has not been studied in vaccines trials. However, as long it is not yet clearly and definitely specified if COVID-19 vaccines completely immunize people from any SARS-CoV-2 infection or just from symptomatic forms of the disease (as the endpoint of the evaluation of the efficiency of these vaccines was the appearance of symptoms, not the number of contaminations), one cannot exclude the possibility that immunized people may still be contagious. So, even immunized people should keep wearing face masks and applying social distancing in public.

yes

It’s not clear till now since this issue has’t been studied in vaccine trials either bec.it’s new or limited no.of cases so we can’t predict that immunized people may still contageous,so they should continue practising preventive measures like wearing masks& social distance.

Dear CEO Dr. Syage!

You raised a crucial point. Based on the available evidence I argue probably yes:

Yours sincerely, Bulcsu Szekely

15 days after second dose of vaccine , they are not contagious

In my opinion even after getting the vaccine we still act as acarriers and can infect others because virus still not able to

replicate and shed coughed out of our nose and mouth Then spread to others including unvaccinated ones‘ but at least vaccination can reduce infection snd mortality rate to some extend.

Have to say yes, because the case is very unclear, in terms of empirical evidence. It is in first line (limited) self-protection for certain identified risk groups.

Have a look at this useful link.

This is encouraging from the New York Times, this morning Jan 18:

Although no rigorous study has yet analyzed whether vaccinated people can spread the virus, it would be surprising if they did. “If there is an example of a vaccine in widespread clinical use that has this selective effect — prevents disease but not infection — I can’t think of one!” Dr. Paul Sax of Harvard has written in The New England Journal of Medicine. (And, no, exclamation points are not common in medical journals.) On Twitter, Dr. Monica Gandhi of the University of California, San Francisco, argued: “Please be assured that YOU ARE SAFE after vaccine from what matters — disease and spreading.”

That is possible.

I think so that

Inconclusive!

This is currently under investigation.

Dear Jack A. Syage , considering the available knowledge, I find the affirmations of Dr. Monica Gandhi and Dr Paul Sax too strong. We have got many surprises with this disease. So, one still needs to be cautious.

I think so that

Transmission is not expected, but we do not have enough data.

I think they can not catch the virus again and they can not be contagious. So they should not continue to wear a mask.

Reinfection reports are still rare but steadily growing around the world, and they're likely underreported. People can catch COVID-19 twice. That's the emerging consensus among health experts who are learning more about the possibility that those who've recovered from the coronavirus can get it again.

It is not clear if the COVID-19 vaccines provide protection against infection (asymptomatic). Unfortunately, the clinical trials were not designed to answer this question. To answer this question, all participants in the clinical study should have been tested for infection by a PCR diagnostic test on at least weekly basis.

Oxford-AstraZeneca vaccine may reduce the transmission of SARS-CoV-2 from those who have been vaccinated.

Article Single Dose Administration, And The Influence Of The Timing ...

Not sure

I think, researchers are investigating whether the issue you asked is really true or false. Better to generalize if multiple studies are done and become conclusive.

May be

Arvind Singh , you are right. The vaccine may "reduce" the transmission. However, it will not completely stop it. So, in my opinion, even those who are vaccinated should keep observing prevention measures.

While getting vaccinated gives people considerable insurance against falling ill with Covid, which is sometimes fatal, if they can still get silently infected with SARS-CoV-2, they might pass it on, potentially sickening people who aren't immune.
