The Spanish vaccination strategy is focused on the administration of the first dose of the Pfizer vaccine to the 30 to 39-year-old group, a group that, due to its youth, usually reports quite a few side effects, unlike the older ones.
What are the side effects of the Pfizer vaccine?
Most of the side effects of the Pfizer vaccine occur after the administration of the second dose, since that is when it occurs. In addition, it is when rarer adverse reactions have been detected, such as myocarditis and pericarditis, or skin side effects such as itching or rash.
After the first dose, those vaccinated are registering milder side effects, nothing or some discomfort in the arm. However, according to the fifth pharmacovigilance report of the Spanish Agency for Medicines and Health Products (AEMPS) it revealed the following adverse reactions.
1. Febrile state (40%)
2. Headache (30%)
3. Muscle aches (22%)
4. Pain in the vaccination area (15%)
5. Discomfort (12%)
6. Nausea (9%)
7. Arthralgia (8%)
8. Chills (8%)
9. Fatigue (8%)
10. Lymphadenopathy (8%).
How effective is generated with the first dose of Pfizer
As published by the scientific journal , the data on the effectiveness of a dose of Pfizer/BioNTech at 13-24 days is 54.4% against symptomatic infection and 51% against infection confirmed by PCR. A small percentage when compared to the immunity achieved after the second dose, which is more than 90%. In addition, the complete vaccination schedule is the safest option to be protected against the Delta variant of the coronavirus.
When is maximum protection achieved with Pfizer?
Thirty-somethings who get vaccinated this July will receive their next dose within 21 days. And they will reach maximum protection against the virus seven days after receiving the second puncture.
