Arab Weather - As the Corona virus continues to spread around the world, and the need to receive anti- virus vaccines increases, some may complain of worrying side effects, but these symptoms are in fact good evidence that your immune system is working the way it is supposed to. , But the effectiveness of the vaccine remains effective even if no symptoms or side effects appear, so what are the most common side effects of anti-corona virus vaccines? Are some symptoms that could be a source of concern that prevents me from receiving the vaccine?
Like any vaccine, COVID-19 vaccines can cause side effects, most of them are mild or moderate and disappear within hours or a few days on their own, and the results of clinical trials have shown that more serious or long-term side effects can occur. Separately.
Common side effects
The reported side effects of the COVID-19 vaccines were often mild to moderate and lasted no more than a few days. The usual side effects include: pain at the injection site, fever, chills and fatigue, headache, muscle pain, and diarrhea. The chances of any of these side effects occurring after vaccination vary according to the type of vaccine.
Less common side effects
Upon receiving the vaccine, the person is usually asked to stay for 15-30 minutes at the vaccination site to monitor the occurrence of any allergic reactions, and the vaccine recipient must inform the competent authority when encountering any unexpected side effects or when the side effects persist for more than three days. Less common side effects that have been reported for some COVID-19 vaccines have included allergic reactions such as anaphylaxis. However, this reaction is extremely rare.
Long-term side effects
Side effects usually occur within the first few days of receiving the vaccine, and since the first mass vaccination program began in early December 2020, hundreds of millions of vaccine doses have been administered, and suffering from side effects after vaccination means that the vaccine is working and your immune system is responding as it should. Therefore, vaccines are considered safe (according to the World Health Organization).
But long-term symptoms may occur because after vaccination, it usually takes a few weeks for the body to build up immunity against the COVID-19 virus. Therefore, it is possible that the person had contracted the infection immediately before or after the vaccination, and he still felt sick, this is because the vaccine did not have enough time to provide protection against the virus.
Can we get infected with the virus from the vaccine?
There were concerns about the COVID-19 vaccines that they transmit the Corona virus to a person, but none of the vaccines based on the live virus that causes the disease, which means that the COVID-19 vaccines cannot cause infection with the Coronavirus.
How many people get side effects?
This is not certain because millions are vaccinated every day, and those who experience side effects may not report them, but in vaccine trials, approximately 10% to 15% of volunteers experienced noticeable side effects.
And when it comes to anaphylaxis - or severe allergic reactions - the rate is now about two to five per million, meaning that about 0.0005% (or less) of those who receive COVID-19 vaccines have a serious allergic response, and the good news is that even when it does occur A serious vaccine allergy, usually occurring within the first 30 minutes .
This is why a person stays at the vaccination sites for 15 to 30 minutes after taking the dose, to make sure that an allergic reaction does not occur. The CDC recommends people who have experienced a severe allergic reaction to a different vaccine or a history of anaphylaxis. By staying for 30 minutes at the vaccination center, others can leave after 15 minutes .
And all places that use vaccines must have epinephrine to deal with any cases of anaphylaxis quickly . More than 150 million doses of vaccines have been given by the end of March, and so far, there is no evidence of any Covid-19 vaccine death.
Do some vaccines produce more side effects than others?
The response of each body differs from the other, so the same vaccine can cause side effects to some and others to feel nothing.
However, some vaccines are more reactive, which means that they usually cause some annoying side effects, but they are not dangerous side effects, and they last for a few hours, and can sometimes last for a day or two.
Is it true that the second doses are stronger than the first in terms of side effects?
The Johnson & Johnson vaccine requires only one dose, but the Pfizer / BioNTech and Moderna vaccine requires two doses, and some people have reported stronger side effects after their second doses, according to Pfizer and Moderna. This is another sign that vaccines are doing what they're supposed to do .
With the first dose, the body produces antibodies, but it also starts producing immune cells called B cells to produce targeted antibodies - this takes time, then with the second dose, these cells sit like a cloned army and can immediately start producing a major immune response, That is, the second dose of the two-dose vaccines builds long-lasting defense power.
When should I get help if my side effects seem severe?
In most cases, feeling discomfort from pain or a fever is a normal sign that your body is building protection, but you should contact your doctor or health care provider if unusual side effects appear or that do not go away after a few days. For example, the redness or pain worsens where you got the vaccine after 24 hours.
