What COVID vaccine might be the safest?

The COVID vaccines are around the corner but they are not all the same.

Some vaccines, such as AstraZeneca’s (cheaper), follow the traditional approach of exposing our immune system to an attenuated pathogen (oversimplified) so our body can develop its own antibodies. There is a decades long track record of testing this kind of vaccines and the existing processes to validate their safety are built upon this knowledge.

Vaccines such Pfizer, Moderna, or BioNTech’s (more expensive) belong to the completely new category of mRNA vaccines. Their vaccines don’t follow this «educational» approach, they don’t show anything attenuated to our immune system, they just TELL to our cells what enzymes they have put together to produce a (spike) protein that will prevent the virus from infecting our cells.

COVID mRNA vaccines have shown a much higher immunity rate than traditional vaccines.

A new kind of vaccine should have had different testing protocols, specially regarding waiting times for side effects

Here is the catch:

  1. As of today, scientists are still debating if one gene encodes one or more enzymes (a gene is a fragment of DNA/RNA’s code).
  2. mRNA vaccines are called that way because they are made of genetic code, they are genetically encoded and we could call them «genetical vaccines».
  3. The incoming COVID vaccines are the first genetic vaccines in history.
  4. This very first mRNA vaccines have been developed and tested in a rush and with the testing protocols originally conceived for the traditional vaccines, not for the new genetic ones (which is reasonable and cautious to assume might cause a new kind of side effects).

Mistakes with DNA/RNA are the cause of cancer.

Think about it, then read about it, then decide if 2-3 months waiting period for seeing if the volunteers has shown or not «symptoms» are enough to rule out all the new possible risks associated with this new kind of vaccines.
