The COVID-19 epidemic is developing very complicatedly, especially with the emergence of new strains such as Delta, Omicron... To prevent epidemics, the best way today is to get vaccinated, especially get enough basic shots and currently Vietnam is starting to get the 3rd booster shot, besides not forgetting to well implement "5K" recommendation.
WHY DO I NEED 3 VACCINE SHOTS TO PREVENT COVID-19?
Vaccination causes active immunity due to the antibodies produced and over time, about 4-6 months after vaccination, the antibodies produced from the two basic doses of vaccine gradually decline, so repeat vaccination ( 3rd booster injection) to increase the level of immune response, causing antibodies in the body to increase again to fight the pathogen SARS-COV-2. Therefore, booster vaccination is very important.

WHAT 3 TYPES OF COVID-19 VACCINE SHOULD I GET?
In this regard, according to the authors, a randomized clinical trial, published in the Lancet in December 2021, evaluated the safety and immune response generated by the allogeneic and boosted vaccine shots. different types. Research shows that allogeneic or different booster injections are effective in enhancing the immune response 28 days after injection. Just like the second shot, the body's immunity will peak two weeks after the injection.

NOTE SIDE EFFECTS WHEN INJECTION OF A BOOST VACCINE
According to the US Centers for Disease Control and Prevention (CDC), in general, the most common side effects of the third injection are fever, headache, fatigue and pain at the injection site. However, most of these manifestations are mild or moderate. Some people also experience symptoms such as diarrhea, vomiting, and muscle and joint pain. There may be other rare reactions such as anaphylactic and allergic reactions. Therefore, vaccination facilities need to ensure the availability of means to prevent shock.

EFFECTIVENESS OF THE 3RD VACCINE
Although there may be side effects, the benefits of the third injection are real. A study by the UK Health Security Agency (UKHSA), published recently, found that 2 weeks after a Pfizer booster dose, protection against infection was 93.1% in those who had previously received an AstraZeneca shot and 94% for Pfizer. However, those who do not feel any symptoms after the injection do not need to worry. NPR news site quoted epidemiology professor Charlotte Baker as saying that if you don't see side effects, it doesn't mean the vaccine is ineffective, but just that "your body's reaction is not shown on the outside."

FACILITIES ORGANIZING THE 3RD VACCINE INJECTION AND WHAT SHOULD BE VACCINATED PERSONS DO?
In addition to regulations to ensure vaccination safety, injection subjects also need to be screened similar to the previous two injections.
.
Injection sites must be arranged to ensure physical distancing. After vaccination, you need to stay at the vaccination site to be consulted and monitored by medical staff for at least 30 minutes.
.
Immediately notify the medical staff if you notice any abnormalities occurring to your body (signs of discomfort, nausea, rash, swelling at the injection site). People who receive the 3rd injection and go home need to monitor their body temperature, take their temperature when they have a fever, use the correct dose of fever-reducing medicine and monitor the response to the fever-reducing medicine. Risk signs include high fever above 39 degrees Celsius, difficulty lowering the temperature or fever lasting more than 24 hours; convulsion; rash; mental discomfort, agitation, drowsiness...; difficulty breathing or when there are other health abnormalities, seek medical attention immediately.
