AstraZeneca’s COVID-19 vaccine will begin on the 26th for workers and residents of nursing hospitals and nursing homes under the age of 65. The Pfizer vaccine is also scheduled to begin on the 27th for medical staff working in hospitals dedicated to infectious diseases, treatment beds for severely ill patients, and life treatment centers. AstraZeneca vaccination will begin in March for about 350,000 health care workers, including hospital doctors, nurses, pharmacists, and medical technicians, as well as 119 paramedics, epidemiological investigation personnel, and quarantine personnel.
Adverse reactions (side effects) after vaccination are usually normal signs that the body is building protective functions and can affect the ability to perform daily activities, but most disappear within 3 days.
Compared to other vaccines, many people feel pain at the vaccination site. In clinical trials, more than 50% of those who received the AstraZeneca vaccine and 84% of those who received the Pfizer vaccine felt pain, most of which were mild. The US Centers for Disease Control and Prevention (CDC) said, “Colding with a clean, cool wet towel or exercising your arms will help reduce pain and discomfort at the injection site.” The redness and tenderness at the injection site worsens after 24 hours or disappears after a few days. If you don’t lose, I advised you to seek medical attention.
In clinical trials of the AstraZeneca vaccine, more than 50% of the vaccines felt pain, headache, and fatigue, more than 40% had muscle pain and malaise, more than 30% had fever and chills, and more than 20% had joint pain. It is similar to the Pfizer vaccine. In the case of nausea, AstraZeneca vaccine was more than 20%, whereas Pfizer vaccine had a very low proportion of 1%. Pfizer vaccine showed swelling and redness at the vaccination site in about 10%.
For both vaccines, most adverse reactions were less than moderate. Of the adverse reactions of the AstraZeneca vaccine, 4% of the local reactions and 13% of the systemic reactions lasted up to 7 days.
The problem is that during adverse reactions, fever and muscle pain may overlap with the symptoms of Corona 19 and may be confusing. The Korea Centers for Disease Control and Prevention said, “Fatigue, headache, chills, muscle pain, joint pain, etc. usually improve within 1 to 2 days without treatment. If it persists for more than 2 days, it is necessary to undergo a test for corona 19 infection, etc.” Fever and muscle pain are among the symptoms of Corona 19 along with dry cough, loss of smell and taste, sore throat, runny nose, and stuffy nose. If you have an adverse reaction to the vaccine, drinking plenty of water and wearing light clothes will help relieve symptoms.
Meanwhile, the American Society of Breast Imaging (SBI) recommended that regular mammograms for breast cancer diagnosis should be delayed before receiving the Corona 19 vaccine or 4-6 weeks after the completion of the second dose. After vaccination, the lymph nodes around the armpits may be swollen. Mammograms at this time can be mistaken as signs of breast cancer metastasis. During the clinical trial, Pfizer vaccine did not ask each vaccinator whether he developed armpit tenderness or swollen lymph nodes, but some reported that these side effects occurred and lasted for an average of 10 days. The same mRNA vaccine, Modena vaccine, resulted in swollen axillary lymph nodes as a side effect in 12% of the first vaccination in the clinical trial and 16% of the second vaccination.

The contents of the CDC guidelines and experts’ opinions on adverse vaccine reactions and precautions are summarized in Q&A.
Q: I have chronic and underlying diseases such as high blood pressure and diabetes. Can I get a vaccine? Also, is it okay to continue taking medicine for diabetes and high blood pressure?
A: Chronic disease patients are likely to become infected and seriously worsen when infected, so they need to be correct when the vaccination sequence is reached. There is no reason to discontinue or change the drug as it has little impact on the effectiveness and safety of the vaccine.
Q: Can cancer patients be vaccinated?
A: Cancer patients and people with severe immune disease have a high risk of developing severe illness when infected with the virus. Vaccination prevents this, so it’s best to get it right in order. The immune response and vaccination effect are likely to be inferior to those of the general population, and there is not much concern about adverse reactions.
Q: I’m a cure for Corona 19, can I get vaccinated?
A: Yes. However, if you have received plasma/antibody (monoclonal antibody) treatment due to COVID-19 infection, vaccination is recommended after at least 90 days to avoid the immune response and interference effects caused by vaccination.
Q: Can I get the COVID-19 vaccine during pregnancy?
A: The results of clinical trials are not yet sufficient, so they are excluded from vaccination until results of clinical trials for safety and efficacy are obtained.
Q: I am a nursing mother. If you get the vaccine, is it okay for your baby?
A: There are no data on the safety and efficacy of the vaccine for breastfed babies. However, it is not expected to be dangerous to breastfed babies, so vaccination is recommended when the order is reached.
Q: Is it possible to inoculate COVID-19 vaccine and other vaccines at the same time?
A: The inoculation interval should be at least 14 days apart.
Q: What should I do if I get a fever on the vaccination day?
A: If you have a fever of 37.5℃ or higher, you should consult a doctor and postpone the vaccination until the fever drops and symptoms disappear. Since this vaccination is carried out by institutions such as nursing homes or hospitals, you can notify the relevant institution of symptoms and adjust the schedule. Later, when individual vaccination begins, the schedule can be changed through the vaccination reservation system.
Q: If workers in nursing hospitals and facilities have fever symptoms after vaccination, they will be confused with the symptoms of Corona 19 and will be worried about whether it is a fire of group infection. What to do.
A: If the fever persists, it may be due to infection with COVID-19 prior to vaccination or for other reasons. It is better to stop going to work and get tested for Corona 19. If you have a high fever of 39℃ or higher, swelling in your face or hands, or allergic reactions such as hives or rashes that interfere with your daily life, you should visit a medical institution and seek medical attention.
Q: Can I take painkillers if I have systemic pain?
A: Taking pain relievers and antipyretics (acetaminophen) may help. If symptoms get worse, visit a medical institution. Avoid taking it before vaccination as it may affect the effectiveness of the vaccine.
