Doctor Nithi replied, When should the third vaccination be given? After being asked a lot | Thaiger Thai News

Mo Nithi came out to answer the question. When should the third dose vaccination be given? Point out that each brand has different injection distances.

Prof. Dr. Nithi Mahanon, Director of Chulabhorn Hospital and the secretary-general of the Royal College of Chulabhorn posted a message on facebook Comments on the third dose of the COVID vaccination along with suggesting the right time to receive the third dose of vaccination

The Facebook message states, “The more is not always the better …..must be right when the time comes. In the past two days, many people have asked about their immunity levels and getting a new round of Covid-19 vaccine to boost immunity. I recommend explaining in detail as follows.

1) For those who have received the inactivated vaccine, Sinovac and Sinopharm, should be immunized. Around the fourth to the sixth month After receiving the second dose of vaccine It should be faster or slower depending on two factors. The first factor is the person’s risk of contracting the infection (eg working in a lot of people or having frequent contact with infected people or people with low immunity, such as immunodeficiency or old age). The second factor is the severity of the outbreak in At that time, for example, if there is a severe outbreak, the fourth or fifth wave, especially in this winter, must be vigilant. It doesn’t matter what type of vaccine is used to boost it, and the level of immunity shouldn’t be a guideline. If you can wait, it should be a second-generation vaccine.

2) For those who have been vaccinated Viral vectors such as Astra Zeneca Johnson and Johnson or Sputnik should be triggered around the sixth to the eighth month after the second dose of Astra Zeneca or Sputnik V, and the first dose of Johnson and Johnson and the Sputnik Light, sooner or later. It depends on the same factors as 1). As with any mRNA vaccine, either Pfizer or Moderna can be boosted with any vaccine as well but should not be the same type for viral vector vaccines. Because the body has a chance to build immunity to the virus that is used as a vector, it is not good to stimulate the immune system.

3) Those who are not in the vaccination group should wait to see if the timing of the booster is available if there is a vaccine specifically designed for the booster. Both the properties and the dosage (dose), the amount of this stimulant is very important. Using the same dose as the first injection may be more than necessary. Shouldn’t be excited to book the first version of the vaccine.

4) If not in the study group, it is not recommended to penetrate the immune level. Because this level of immunity cannot directly indicate the level of protection against the vaccine (there are many missing unknown unexplained links), because follow-up studies of the proposed immunity levels show that in the same group and received The same vaccine has too many different levels of immunity to explain. (If anyone looks at the numbers on the graph, it can be seen that the level of immunity when presented is vertically indicating the level that can be measured is a log scale because it has to show values ​​from zero to tens of thousands. The measurements of all vaccines studied ranged from very low to very high. The fact that we saw the results of it being clustered together was actually very scattered. Those who understand statistical numbers will understand that these results are not easily divisible.) Concluding that immunity levels can only be used as research indicating that the vaccine’s immunization could be “some” (but not the entire immune system of people who have not yet developed a vaccine). There is a memory level of immunity, etc.) It is useful to study the selection and determination of vaccine types. But it doesn’t say the level of the body’s defense against infection.

5) All vaccines currently available None of them protect against delta strains (and besides, The degree of infection depends on both the level of the virus and the amount of infection, but all types can prevent severe symptoms and death. 100%), so should change the concept that We vaccinate each other to prevent serious illness and death. and widespread spread

6) Prompt detection and prompt treatment already initiated, whether antiviral or antibody cocktail. It will make when infected and get the drug faster, it heals faster and there are no serious symptoms that need to be hospitalized as well.
Soon we will be able to live with it comfortably. But still have to help each other to win another story is the vaccine in children. Because we as adults still want society to return to normal (new), especially children should return to school as soon as possible.”
