Vaccine development presents many challenges to making them safe and effective, and this case is no exception. Therefore, it is important to know the limitations and problems that may be encountered so as not to become overconfident in its effectiveness and delivery times. These are ten of the many reasons why we must be realistic and not wait for a miraculous vaccine to appear that will free us from this pandemic immediately.

The normal process to make a vaccine is between 10 and 15 years. You cannot expect to have a perfect one in less than a year and that will automatically allow us to return to our previous life.
For example, the shortening that we are seeing in the preclinical research phase in which the vaccine is studied in cell cultures and animals is something unusual and a reflection of the urgency Middle East Phone Number List to find the vaccine. 2. It has to protect in humans A woman prepares medication for COVID-19 patients in a hospital. A woman prepares medication for COVID-19 patients in a hospital. Reuters It's easy to say, but it's where most candidates often fail. A vaccine can be very well designed, safe, 100% protective in animal models, and induce a strong immune response and neutralizing antibodies, but offer a much lower level of protection than expected when tested in humans.
Wanting is not always power temperature control In 1984, when the human immunodeficiency virus (HIV) was identified as responsible for the AIDS pandemic, the United States Secretary of Health and Human Services declared that the vaccine would be available within 2 years. Today, 36 years later, there is still no vaccine. Vaccine development does not always bear fruit. Although comparing HIV with this new coronavirus is not the most accurate because they are very different, there are times when – no matter how hard you look – you cannot find a way to develop an effective vaccine. In fact, although there are good vaccine candidates with promising results in animal models, so far there is no vaccine available for any of the other coronaviruses that affect humans. The reasons are multiple, from lack of commercial interest to the observation of adverse effects in different studies.
