Yesterday (23 Jan 2021) Dr. Sirirak Changrob, a postdoctoral researcher at the University of Chicago researching influenza vaccine and the immune system against COVID-19, published a message on Facebook. Siriruk Ch Share your experience with Pfizer BioNTech’s COVID-19 vaccine, complete with 2 doses.
Dr. Sirirak receives the vaccine in Chicago. After the first dose passed 20 days ago among the elderly who gradually received the first dose By making an appointment to receive the vaccine from the date of receiving the first dose Before having to go check in to the injection room The nurse will ask for symptoms after receiving the first dose of vaccine.
The general question is: Have you ever had a history of severe allergy? 90 days before, Have you ever been tested for COVID-19 infection? Yoo received the second dose, congratulations, and put on a sticker I got my COVID-19 vaccine! On our work card

Dr. Sirirak stated that since receiving the first needle The vaccinated person will be given a Vaccination Record Card with name information. Date of birth Date of first and second vaccine Vaccine brand obtained And the production lot Keep it with you to help you remember when and what brand of the COVID-19 vaccine had been. Which sees this card as important in the future that may be used as a travel companion
For the first 2 hours of symptoms, nothing. After 8 hours, I feel a little hot. And pain at the injection site Not different from the first dose Wait and see symptoms the next morning. All friends said Definitely heavier than the first dose
One needle cannot be taken. Recommend accepting the 2nd needle as scheduled
Dr. Sirirak also stated that a second vaccination should be on schedule. This is because most vaccines have a limit on how late the next vaccine is received, up to a few days. Also, in trials, neither Pfizer nor Moderna’s vaccines were designed to be vaccinated in one dose. To obtain maximum effectiveness, only the second dose must be obtained.
Pfizer claims the vaccine will provide maximum protection only after the second dose has been taken 7 days, the time between the first doses. With the second hand spacing 21 days on the Moderna side is 14 days, the period between the first hand With two needles except for 28 days
If anyone is not sure that they can pick up the 2nd needle on time Well, don’t get the first dose. Right now, there are Johnson and Johnson things that are rushing to pick up the results of a single-dose vaccine. Might get good news soon.
Dr. Sirirak also recommends caution for people with underlying diseases and must take medication regularly that Always consult your doctor before getting any vaccine. So as not to prevent the effectiveness of drugs and vaccines against each other. People who are afraid of getting a fever and taking medication should not do it because it will affect the immune system’s function of the vaccine. But if you have a fever after vaccination, you can take a pain reliever and fever reducer.
People who have been infected with COVID-19 can still be vaccinated. To confirm that there is effective immunity However, you should not receive the vaccine while infected with COVID-19, but only after recovering and returning to your normal life.
Complete vaccination But still must have a mask?
Recently, Thai PBS online interviewed Dr. Sirirak found that the latest symptoms are still crowded, but not fever, arm pain at the vaccination area only. No other symptoms Ms. Sirirak emphasized that even though she and her friend had received 2 vaccines, they still had to wear a mask. And spaced the same Since most people are not immune While the available vaccines are vaccines that prevent disease only
We can still get infected if we don’t take good care of ourselves. And spread to other people as well, so have to wait until 60% of the population is immune. To return to normal life

Dr. Sirirak, as a researcher of influenza vaccine and COVID-19 immune system, told Thai PBS Online that The vaccine is most effective 7-14 days after the second injection, but when people around you are not immune. Those who have received the vaccine are still at risk of getting the infection. If social distancing is not followed
Have to wait and see the Israeli model that is now 20% vaccinated, almost 30% already, which Israeli said. After injection, the number of cases decreased. Because many people have immunity Therefore less chance of infection The transmission of the infection will be reduced accordingly.
Common side effects after vaccination
Many people may be concerned about side effects after receiving the COVID-19 vaccine. Dr. Sirirak stated that the most common symptoms seen in trial subjects were: Have flu-like symptoms Who didn’t get the flu Symptoms include aches, aches, muscle aches, chills, joint pain, fever, heat, which is a good sign that your body is immune to the vaccine.
According to the results of both Pfizer and Moderna volunteers, approximately 50% had primary side effects (as above) after the first dose and 70-80% had symptoms after the second dose. And about 10-20% of them have to take sick leave. Can’t go to work
Now, as far as I asked the friend who received the second needle, everyone answered in the same voice that it was more severe than the first. Pain, headache, heat, some people have enlarged lymph nodes under the armpit. Points near the injection site But these symptoms disappear within 48 hours.
