COVID vaccines: what are their benefits and potential side effects

Development vaccine safe and effective helped slow the coronavirus pandemic. A study conducted in 141 countries found that Vaccination prevented 2.4 million deaths according to researchers from University of Southern California (USC) And Brown University, USA.

Since the virus is still circulating in the world, booster doses are recommendedespecially in people at increased risk of serious illness.

Some vaccine uses may have side effects. However, The benefits of immunization have always outweighed the risksas demonstrated in clinical trials that evaluated inoculants prior to their approval by national regulatory authorities.

I agree with you US Centers for Disease Control and Prevention (CDC)Vaccines, like any medicine, can have side effects.

“Side effects following COVID vaccination vary from person to person. The most common ones are usually mild, such as pain in the area where the vaccine was administered, CDC experts said.

Side effects usually disappear within a few days and tend to be mild and temporary., for example, after routine immunization, which was before COVID. “Even if you don’t experience any side effects, your body is building up a defense against the virus that causes COVID-19,” CDC experts explained.

Severe allergic reactions after vaccination are rare but can be life-threatening. Symptoms may include:

• Anaphylaxis, which is a life-threatening reaction that must be treated with epinephrine (EpiPen) and may require hospitalization. Signs include shortness of breath, difficulty breathing, or low blood pressure; and sometimes hives.
• Inflammation of the airways, including the tongue, uvula, or larynx.
• A generalized skin rash that affects the skin and internal parts of places such as the mouth or nose and requires hospitalization.
• If such reactions occur, seek medical attention immediately.

Best regards to COVID messenger RNA vaccinesThe CDC specifically reported that common side effects following use may include: pain, discomfort, redness at the injection site, fatigue, headache, muscle pain, joint pain, chills, fever, nausea and vomiting.

In infants and young children, common symptoms include irritability or crying, decreased appetite, and drowsiness.

The vaccine “ChAdOx1-S”, developed by Oxford University and company AstraZenecain the United Kingdom, where a non-replicative viral vector platform was used.

The company recently admitted that one of the side effects may be related to thrombotic syndrome with thrombocytopenia. He admitted this in a number of legal documents submitted as part of the trial he faces in the Supreme Court Great Britain.

In 2021, the company’s scientists published a report, “Very Rare Thrombosis with Thrombocytopenia after Second Dose of AZD1222: Analysis of a Global Safety Database.” The document notes that “very rare cases of blood clots with thrombocytopenia syndrome have been reported since the launch of the vaccine.”

A link between the vaccine and the disease was also found in a study published in 2022 by a scientific journal. British Medical Journal. During the work, various suspicious cases were analyzed in France, Germany, the Netherlands, Spain, the UK and the USA.

However Global Advisory Committee on Vaccine SafetyA panel of experts providing independent and evidence-based advice to the World Health Organization (WHO) on the safe use of vaccines reviewed the following in 2022: “A new type of very rare adverse event known as thrombosis syndrome with thrombocytopenia following administration of this vaccine. This syndrome involves serious and rare bleeding disorders associated with low platelet counts.”

Committee experts also expressed the opinion that “in countries where transmission of SARS-CoV-2 is currently observed, The benefits of vaccination far outweigh the risks.“given the protection provided by the COVID-19 vaccine.”

Medicines Regulatory Authority in Great Britain He also informed the public about the possibility of side effects with the vaccine developed by Oxford/AstraZeneca in 2023.

“It was noticed extremely rare cases blood clots with low platelet counts (thrombocytopenia thrombosis syndrome) after vaccination with the AstraZeneca COVID-19 vaccine. This included some severe cases with blood clots in different or unusual places, as well as excessive blood clotting or bleeding throughout the body. Most of these cases occurred in the first 3 weeks after vaccination, but some of them were registered after this period,” he said.
