Vaccine affects HRV

Question: I took both the Covid and flu vaccines yesterday.
Can I assume that the stress of the night is due to these? Yesterday should not have been such a night otherwise. I ate properly and not late, exercised properly, etc.

Answer: Hi! You are probably right. I have received several such feedback in connection with the autumn flu and Covid vaccination. It seems to me that it is the flu vaccine that has the most impact. The reason is probably that the immune system is actively working on the task it has been given through the vaccine. The goal of vaccines is to give the immune system a mild taste of the infection that it is supposed to protect against. After such an encounter, antibodies will be formed that will more easily perceive when the real virus arrives and will thus be able to recognize it more easily and fight it more effectively.

It is important not to have too much stress before and after a vaccine in order to get the best possible effect. For example, research has found that sleep is important for getting the maximum effect from the vaccine. In this study, those who received too little sleep had only half the effect of the control group. https://www.uchicagomedicine.org/forefront/research-and-discoveries-articles/not-getting-enough-slee…

Poor sleep is not the only thing that causes stress. In general, a person exposed to stress will have less energy left over for the work of the immune system, which is reflected in the response to vaccines.

Conclusion: to get the maximum effect from vaccines, we should calm down before and after vaccination. In addition, it is important to be aware that an immune response to a vaccine is a load that affects HRV and your available energy afterwards to varying degrees. For example, I have seen a young person with a body battery of 25 instead of the usual 100 after the mandatory HPV vaccine.
