Dubai- Can you skip the quarantine if you catch the Coronavirus after receiving the vaccine?
And people who have been fully vaccinated can now skip quarantine even if they are exposed to the Corona virus, according to new guidelines issued by the US Centers for Disease Control and Prevention. But at the same time, the agency also acknowledges that many researchers do not know how vaccines affect transmission.
The new guidelines apply only if at least two weeks have passed since the final dose, and not more than three months after receiving that dose, and provided that people do not have any symptoms.
It is important to note that the CDC does not indicate that someone who has been vaccinated cannot spread the Corona virus, within the first 90 days of being fully vaccinated, Kristin Nordlund, a spokeswoman for the US Centers for Disease Control and Prevention, told CNN by email. We are not suggesting that the expected protection from Coronavirus vaccines fades after 90 days.
Do you feel disoriented? Don’t worry, you are not the only one.
Nordlund said there is currently limited information about how much coronavirus vaccines reduce transmission or how long protection takes. She added: “Nevertheless, we know that quarantine can be extremely devastating to the individual as well as society,” explaining that the benefits of avoiding unnecessary quarantine, especially for those who have been fully vaccinated, are likely to outweigh the unknown risks of transmission from a person who has been vaccinated. .
But that doesn’t mean that people can stop wearing a mask, turn away from others, and follow other US Centers for Disease Control and Prevention guidelines. People are also not exempt from the testing requirements for those returning from abroad.
While the guidelines indicate that people who have been vaccinated are less likely to transmit the virus, the Centers for Disease Control clarifies that vaccine trials have focused largely on preventing cases of symptoms of the Coronavirus. This does not mean that people cannot catch and spread the virus without symptoms. But experts say this is more difficult to measure.
Indirect transmission measure
Direct measurement of the transmission of the Corona virus is difficult, so researchers use benchmarks to estimate the likelihood of a person transmitting the virus.
One possible alternative is viral load, that is, the amount of virus that spreads through their bodies. Research has shown that people with lower viral loads are less likely to transmit the virus.
A recent study in Israel found that people who were infected 12 to 28 days after their first dose of the “Pfizer” vaccine had four times less viral loads than if they were infected within the first 12 days, while the study was not subject to peer review, and does not include data yet. The second dose.
Another study on the AstraZeneca vaccine indicated that it could affect transmission, but it did so using a different scale. Researchers collected nasal swabs from trial participants in the United Kingdom every week, and found that the rate of positive tests decreased by half after two doses of the vaccine.
Neither of these studies measured transmission directly – for example, by tracking contacts of study volunteers to see if they had been infected. But it does give a positive sign for what experts have suspected for some time, based on trials of vaccines for other diseases.
Limited data, limited recommendations
Dr Megan Rane, assistant professor of emergency medicine at Brown University, said that more studies testing people who were regularly vaccinated for the Coronavirus, would give doctors a better understanding of how vaccines affect transmissibility and for how long.
This is partly why the recommendation is only in effect for up to three months, because the CDC and vaccine makers don’t have a lot of data that gets published longer than that after people are vaccinated.
