The efforts of ministries of health, the World Health Organization and regional organizations to respond to the COVID-19 pandemic around the world include providing and updating guidance and advice on critical interventions, distributing vital medical supplies to those in need along with the competition for time to develop and deploy safe and effective vaccines.
According to the official website of the World Health Organization, Vaccines save millions of lives every year. Vaccines train, prepare, and enhance the body’s natural defences, the immune system, to recognize and combat the viruses and bacteria that target them.
After receiving the vaccine, if the body is subsequently exposed to those disease-causing germs, it is immediately ready to destroy them and prevent severe cases of illness.
Corona vaccines are “expressive”
The main preventive measures
The World Health Organization has stated that there are many safe and effective vaccines that prevent people from becoming seriously ill or dying from COVID-19.
The official account of the World Health Organization noted that receiving vaccinations is part of the measures to prevent the risks of the Covid-19 pandemic, to other main preventive measures, including staying at a distance of at least one meter from others, using the facility when coughing or sneezing, cleaning hands frequently, and wearing Protective mask, avoid staying in poorly ventilated rooms, and open windows for good ventilation in any buildings.
Evaluation of safe and effective vaccines
According to a report by the World Health Organization, as of November 15, 2021 the following COVID-19 vaccines have been evaluated for meeting the necessary safety and efficacy criteria:
• AstraZeneca/Oxford Vaccine
• Johnson and Johnson
• Pfizer / Biontech
The report added that some local authorities have also carried out evaluations of other vaccine products against COVID-19, which are used in their countries independently.
The report indicated that there is a need to receive the available vaccine as soon as the opportunity becomes available and as soon as possible. The report indicated that approved COVID-19 vaccines provide a high degree of protection against severe or severe cases of COVID-19 disease or death, even though no vaccine is 100% protective.
The World Health Organization renewed its guidance, saying that COVID-19 vaccines are safe for most people 18 years of age or older, including those with chronic conditions of any kind, such as autoimmune disorders, which are priority groups for vaccination to Patients with high blood pressure, diabetes, asthma, lung, liver and kidney diseases, as well as stable and controlled chronic infections.
The World Health Organization recommended that the case be discussed and a doctor consulted if the person suffers from a weak immune system and in cases of pregnancy and breastfeeding, as well as those who suffer from a history of severe allergies, especially to vaccines (or any of the components of vaccines) or those with a very weak health in general.
Children and teenagers
Children and teens have a milder exposure to COVID-19 than adults, so unless a child or teen is in priority groups or is at increased risk of severe COVID-19, getting vaccinated is less urgent than older adults, who have Chronic health conditions and health workers.
The WHO website indicated that more evidence is needed about the use of the different COVID-19 vaccines for children in order for the WHO to make general recommendations on vaccinating children against COVID-19.
Ages 12 to 15 years
The World Health Organization’s Strategic Advisory Group of Experts (SAGE) concluded that the Pfizer/Biontech vaccine is suitable for use by people 12 years of age and older. Children aged 12 to 15 at high risk, along with other priority groups for vaccination, can be vaccinated with the Pfizer/Biontech vaccine.
Vaccine trials for children are still ongoing and WHO will update its recommendations when more evidence is obtained or if the epidemiological situation requires a change in policy.
After receiving the vaccination
The guidelines of the International Organization recommend that the recipient of the vaccine stay in the designated place at the vaccination center for at least 15 minutes after the injection, and in the event that the vaccination recipient experiences any unusual reaction, the specialized personnel of the vaccination center will be able to help him.
Recipients of the first dose of the vaccine should check when the next dose is due before leaving, and check with their health care provider to make sure if and when the person needs to get a second dose, especially since second doses help boost the immune response and strengthen immunity.
The World Health Organization website stated that in most cases, side effects are minor and normal, and common effects after vaccination that indicate that a person’s body is building protection against Covid-19 infection include the following:
• Mild fever
• Muscle or joint pain
But the recipient of the vaccine should contact the health care provider if redness appears in the area of the vaccine injection and if it increases after 24 hours, or if the side effects do not disappear after a few days.
If the vaccine recipient suffers from an immediate severe allergic reaction to the first dose of the COVID-19 vaccine, he should not receive additional doses of the vaccine, noting that it is extremely rare for serious health reactions to occur due to vaccines.
Before and after receiving the vaccine
It is not recommended to take painkillers such as paracetamol before receiving the Covid-19 vaccine to prevent side effects, because it is not known how the painkillers can affect how well the vaccine works. But paracetamol or other pain relievers can only be taken if the recipient experiences side effects after the vaccination such as pain, fever, headache or muscle aches.
While the COVID-19 vaccine will prevent severe or serious illness or death, it is still unknown to what extent the vaccine prevents infection and transmission of the virus to others. The more the virus can be trapped and the chances of it spreading, the greater the ability to reduce its ability to mutate.
The World Health Organization advised that it is necessary to continue to take measures to slow and eventually stop the spread of the virus, as follows:
• Maintain a distance of at least one meter from others
• Wear a protective mask, especially in crowded, closed and poorly ventilated places
• Clean hands frequently
• Cover any coughing or sneezing by bending the elbow in front of the mouth and nose
• Ensure that there is good ventilation by opening the windows when the person is inside the house with others, or the workplace.
