It may be comforting to get the Covid vaccine in the end. This is the first step in returning to life before the pandemic-but the last word is that this is not an excuse to relax your guard.
In fact, experts say that we are at a watershed in the pandemic.
The director of the CDC, Dr. Rachel Varensky, said that although vaccination eligibility is expanding, at a press conference on Tuesday, the United States is facing “imminent doom”
Therefore, although it is said that a fully vaccinated person can hang out with other vaccinated people without a mask indoors, even a fully vaccinated person can have a faceless party with someone from another family who has not been vaccinated (as long as They do not have an increased risk of serious illness or death), and many safety measures are still more important than ever.
Experts say that even for those who have been vaccinated, avoid gatherings on medium or large occasions, delay travel, wear masks and maintain social distancing.
This is why there are still risks even if you have been vaccinated:
You cannot get full immunity immediately
After the vaccine is given, it takes several weeks for your immune system to increase its protection against the virus.
Since Moderna and Pfizer’s Covid vaccines need to be injected in two separate injections, you can only get partial immunity about two weeks after the first injection, and you can get further immunity only two weeks after the second injection.
In clinical trials, Johnson & Johnson’s single-dose vaccine has a protective effect on Covid-related hospitalizations and deaths starting 28 days after vaccination.
According to the CDC, this is why it is considered Covid’s “fully immune” vaccine two weeks after the second two doses of vaccine or two weeks after receiving a single dose of Johnson & Johnson vaccine.
The CDC says that currently, 16% of the population in the United States has been fully vaccinated.
Even if fully vaccinated, you can still get Covid and spread it to others
As with any vaccine, even people who receive two doses of the vaccine at the same time may be infected by Covid, which is called a “breakthrough case.”
For example, in Washington State, public health officials have reported 102 breakthrough cases since February 1, accounting for approximately 0.01% of the state’s vaccinated population. In February, four people in Oregon were also found in South Carolina and Minnesota, and both of their vaccines were positive for Covid/Breakthrough cases.
Usually, in the above cases, people with breakthrough disease have milder symptoms (if any).
There are still questions about whether the Covid vaccine can stop the spread of the virus.
The CDC said: “There is increasing evidence that fully vaccinated people are less likely to be infected asymptomatically, and may be less likely to infect SARS-CoV-2 to others. However, further The investigation is still ongoing.”
A CDC study published on Monday found that, for example, a dose of Pfizer vaccine or Moderna vaccine is 80% effective in preventing Covid infection.
However, the vaccinated person may have very mild symptoms, or even no symptoms at all, and still spread the virus to other people.
Even mild cases will produce variants, which may reduce the effectiveness of the vaccine and hinder the herd’s immunity
Even in partially or fully vaccinated people, Covid cases are milder, any spread of the virus will still encourage the emergence of new variants with mutations. This is a problem with several reasons.
First, variants can be more infectious and even more lethal.
Walensky stated on March 24 that Covid variants and loose social distancing measures appear to be driving an “avoidable surge” of US cases. The British variant B.1.1.7 is better than SARS-Cov-2. Valensky said on Wednesday that B.1.1.7 is becoming the main strain in the United States, accounting for 26% of cases.
In addition, early data suggests that the vaccine may be effective for some variants, but not others.
Bottom line: Using protective measures to stop the virus from spreading is the key to ensuring that no more mutations will occur.
