How to reduce the risk after being vaccinated with COVID-19?

In recent days, many parents have been worried about the reaction after vaccinating their children with COVID-19. Learn about post-injection reactions and how to deal with them in the article below.

1. What is the reaction after vaccination?

There are two reactions after injection:

-One is a local response:
Local reactions after injection are common and include controlled immune responses to antibodies, such as:

-Local pain

– Muscle pain

– Tired

– Headache…

These are common non-dangerous reactions, which usually disappear on their own within a few days or after taking 1-2 doses of analgesics and antipyretics.

These reactions depend on each person’s location, production technology, ingredients and characteristics of the vaccine…

-The second is allergic reaction:
The latter form is dangerous and is usually the cause of death. This is a hypersensitivity reaction of the immune system, also called an allergic reaction.

Allergic reactions usually occur within a few minutes to 1-2 hours after the injection (or contact with allergens: drink, eat, smell, even touch…). Very few cases will occur within a few days.

Therefore, Decree No. 104/CP-2016 on the safety of vaccination stipulates:

Vaccination activities must be carried out in institutions that meet the vaccination requirements (sufficient human resources, equipment, emergency medicines…). Do not inject yourself at home.

After the injection, observe at the vaccination facility for at least 30 minutes.

The vaccinators must explain and instruct the vaccinators to continue monitoring after leaving the vaccination facility for at least 24 hours…

All these requirements are only the purpose of early detection and correct management of allergic reactions.

2. How to detect allergic reactions after vaccination

There are many articles sharing very detailed information about allergic reactions. Almost all deaths after vaccination are related to allergic reactions.

The most important thing in the management of allergic reactions is early diagnosis and correct management. If diagnosed early and dealt with properly, patients with allergic reactions are unlikely to die.

To understand what an allergic reaction is, it is important to understand its symptoms and course. Allergic reactions are also divided into 4 degrees:

-Level 1: Erythema clusters, clusters, then spread, eyelid edema, facial edema…

-Level 2: More shortness of breath, shortness of breath or abdominal pain, and frequent loose stools.

-Grade III: persistent hypertension (>140/90 mmHg) or hypotension.
