Those who have already been vaccinated can help science advance the fight against Covid. Reporting adverse reactions to health authorities and manufacturers is essential for optimizing package insertion and even the use of fortifying agents. This is called phase IV vaccines.
Some pain, a little fever and a feeling of weakness are the body’s common reactions to new elements that will stimulate the immune system to fight the coronavirus and can last up to three days. According to the National Health Surveillance Agency (Anvisa), which is responsible for monitoring, all vaccines being applied have already passed safety and efficacy tests in small and large groups of volunteers. Now, with comprehensive application, the contribution to further improvement of the immunization program will come.
Manufacturers are legally and contractually obligated with Pharmacovigilance to report adverse reactions. They provide space on websites for those vaccinated to report whatever they think is necessary. Health services and professionals can also contribute. In addition to the channels of manufacturers and the Ministry of Health, Anvisa receives reports on the VigiMed platform.
Through its pharmacovigilance investigations, the Ministry of Health has determined which vaccines should be used for pregnant women with comorbidities and also include reactions such as nausea, drowsiness and diarrhea in the packages.
