How long is the first dose of the vaccine effective? And honestly, would you advise me to take the second one?

Hello,

In fact, the first dose only protects for a few months. The level of antibodies (called humoral immunity, which is a relatively short- to medium-term immunity) against SARS-Cov2 produced quickly goes down after about 4 months. In addition, cellular immunity, which is long-term immunity, becomes effective only after 2 full doses of vaccine

But I would love the opportunity to address your concerns to the best of my knowledge. Can you tell me what those fears are?

These are legitimate concerns. Here is what I know about them

The majority of studies involving vaccines (regardless of the type of vaccine), are generally short term (about 2 months). COVID-19 vaccines are no exception. The logic behind this is that vaccines are products that are rapidly eliminated by the body (usually within a few days). Any product introduced into the body (be it a drug or vaccine, food product, etc.) is eventually eliminated in one way or another by the kidneys or liver. We know that the mRNA structure in COVID vaccines is eliminated after about 4-5 days from the body. So even though the product is no longer present, the antibodies and immune cells created (which are products of the body remember) remain and cannot be harmful to the body. It is very important to know the long-term effects of a drug that would be taken every day, for example, because it will always be present in the blood. But in this case, it is very, very unlikely that any effects will occur beyond 3 weeks after the vaccine.

Safety data are often the first data collected. Not all studies on current vaccines are complete. However, the missing data are not safety data (if this had been the case, the product would not have been able to obtain emergency authorization, proof of safety is a requirement before obtaining this authorization), but rather data concerning certain types of populations (such as populations under 12 years of age for example). Clinical experience has shown us that the administration of these vaccines is safe during pregnancy and breastfeeding. In fact, the Canadian Society of Gynecology and Obstetrics recommends the COVID vaccine to all pregnant and breastfeeding women at all stages of pregnancy

The mRNA strand that is injected does not have the potential to alter the genome. The genes are located inside the nucleus of the cells while the injected mRNA strand is designed to remain on the surface. The lipid nanoparticles that carry the mRNA strand disintegrate upon contact with the cell membrane. None of the products in these vaccines can harm you or your baby, so you can rest assured. I know that there is a lot of information on the web, I see it too :), but you are right to validate with health professionals

The second dose can cause more fatigue, headaches, aches and pains. The effects can last 12 to 24 hours. It's like having a bad flu

I hope I have answered some of your questions about vaccines. If you still have questions, you can ask me. I have done a lot of research on these vaccines and have also vaccinated many patients (including pregnant women)
