FAQs before injecting the COVID-19 Vaccine
Infection after vaccination, infertility, new variations, complications, injection for pregnancy, effective time, face mask after vaccination, who should not be vaccinated, dieting.
1. Can I get COVID-19 after vaccination?
Maybe. No vaccine is 100% effective against the disease. According to the study, three weeks after the first dose of the vaccine, 7 out of 10 people are protected to some degree. However, it may not be enough to protect against COVID-19 so a second dose is needed. As with all immunizations, the COVID-19 vaccine may not protect everyone, and so it is necessary to continue to follow local rules, wear masks, washing hands, and social distance.
2. Does the Coronavirus vaccine cause infertility?
NO. There is currently no evidence or data to prove that the coronavirus vaccine can cause infertility. "COVID-19 vaccine will not be approved if it causes fertility in both men and women": The researchers say. Further clinical trials are planned and relevant information will be made available to physicians or healthcare professionals.
3. Should I get an injection when I have COVID-19 and recovered?
YES. As recommended, it is essential to get the COVID-19 vaccine regardless of whether you already have COVID-19 or not. Even after you have recovered from SARS-CoV-2 infection, you are still at (although rare) risk of being reinfected with COVID-19. Immunization is the safest, simplest, most economical, and effective method of protecting the body from the global virus.
If you have been treated for COVID-19 with monoclonal antibodies or convalescent plasma, you should wait 90 days before getting the COVID-19 vaccine. Please clarify your situation with your doctor to receive the most accurate advice.
4. Is the COVID-19 vaccine effective with the new variants?
YES. The COVID-19 epidemic is having complicated and unpredictable developments with multiple sources of infection, multiple strains, and multiple outbreaks spreading rapidly in many localities. Building herd immunity thanks to a COVID-19 vaccine is considered a safe tool to help end the pandemic and return to normal life soon.
Current data suggest that the COVID-19 vaccine is effective against most of the new variants. With two new variants of the SARS-CoV-2 virus, India (B.1.617.2) and UK (B.1.17), the COVID-19 vaccine can produce the same protective effect as the original strain.
5. What are the complications after vaccination?
The World Health Organization (WHO) affirms that the COVID-19 vaccine is safe and protects the body from attack, complications, and death from the SARS-CoV-2 virus. After getting the vaccine, you may experience some mild side effects, which are good signs that your body is being protected. This means the vaccine is working and your immune system is responding normally.
However, if you do not experience side effects after receiving the Covid-19 vaccine, it does not mean that the vaccine is not effective. In other words, each person will experience a different reaction after receiving the vaccine. This is really one of the frequently asked questions before getting the Covid-19 vaccine at vaccination centers.
Like any vaccine, the COVID-19 vaccine can cause mild to moderate side effects such as fever, headache, chills, muscle aches, fatigue, nausea, dizziness, tachycardia… These symptoms may appear after the injection, disappear on their own after a few days, and do not affect health.
It should be emphasized that serious complications from the COVID-19 vaccine are extremely rare, while the benefits from vaccination are many times greater. When experiencing anaphylactic reactions such as high fever, convulsions, sepsis, abscess, anaphylactic reaction, thrombosis, etc., the vaccinated person should immediately contact the nearest doctor or hospital to diagnosis the cause for timely treatment and treatment.
6. Is it safe for children to have injections?
YES. The COVID-19 vaccine has been shown to be safe and effective beyond the expectations of the World Health Organization (WHO). After being vaccinated, your child may experience side effects that are common and go away on their own after a few days. COVID-19 Vaccine is indicated for people 18 years of age and older, not for younger people. For children and adolescents under 18 years of age, scientists around the world recommend that the COVID-19 vaccine is not/should be given for the following reasons:
- The vaccine has not been tested enough to determine its safety and effectiveness in children and adolescents under 18 years of age.
- Children with COVID-19 often have no symptoms or are milder than adults.
- Children have low rates of COVID-19 and mortality.
7. Injection for pregnancy or not?
The COVID-19 vaccine is not recommended for pregnant and lactating women, and there are currently very little data to assess the safety of the vaccine during pregnancy. However, women who are pregnant are at higher risk of complications from COVID-19. On the other hand, pregnant women can still be vaccinated if the benefits of vaccination outweigh the potential risks from the vaccine. For this reason, pregnant women with high risk factors for infection with the SARS-CoV-2 virus (e.g. health care workers) may be considered for vaccination after consulting with their healthcare professional doctor.
8. How long is the vaccine effective?
Because the COVID-19 vaccine is a new one, it's not yet time to confirm how long the protection lasts. However, the COVID-19 Vaccine has been given to thousands of people in clinical trials, all of which were carefully monitored for 12 months.
9. Face mask after vaccination is neccesary?
Not everyone has the same immune response to vaccination. With most vaccines, the protection rate is never 100% absolute, the same with the COVID-19 vaccine. Therefore, there is still transmission of infection in people who have had enough COVID-19 vaccine (uncommon).
It should be noted that, after vaccination, vaccinated people still have to strictly follow infection prevention measures: Masks - Disinfection - Distance - Do not gather - Medical declaration.
10. Who should not be vaccinated?
According to the World Health Organization (WHO), each country needs to vaccinate at least 70% of the population to achieve herd immunity. Like other medicines, the COVID-19 vaccine can cause some side effects and is not suitable for certain people. All people who have had a severe allergic reaction to any of the active ingredients or excipients listed in the vaccine ingredients section MUST NOT get the vaccine.
Besides, it is necessary to be cautious with vaccination with subjects, such as:
- If you have ever had a severe allergic reaction (anaphylaxis) after a certain vaccine in the past.
- If your immune system is weakened (immunosuppressive) or you are taking medicine that weakens your immune system (such as high-dose corticosteroids, immunosuppressants, or cancer drugs).
- If you currently have a severe infection with a high body temperature (above 38°C/100.4°F).
- If you have bleeding/bleeding problems or bruising, or if you are taking blood thinners (anticoagulants).
In case if you are not sure about any of the above, talk to your doctor or healthcare professional before you are vaccinated.
11. Dieting after vaccination is important or not?
Experts said that although there is no big impact, a simple, reasonable, and scientific diet and exercise before and after injection will help promote the best effects of the vaccine. Vaccinated people should avoid drinking alcohol before and after vaccination, eat plenty of foods rich in fiber and whole grains, drink enough water, get enough rest, and should eat before vaccination. In particular, you can resume normal activities after vaccination if your health allows.
