Diagnosis of COVID-19 after receiving the varicella and measles vaccine?
Hello Dr.
Hsiao, I have twin babies who just turned one year old.
They received the varicella and measles vaccine on July 14.
Baby B had a fever from July 16 to July 18, and Baby A also developed a fever on July 18.
During a doctor's visit on July 18, they were tested and found to be infected with the COVID-19 virus.
Baby A had a fever from July 18 to July 20, but after taking medication at home, the fever gradually subsided, and now they only have a cough and some nasal discharge, continuing to take cough syrup.
However, Baby B had a slight fever again on July 22 and 23, reaching over 38°C, but after taking antipyretics, the fever subsided.
Starting on the night of July 24, Baby B developed a rash on the body, neck, and face, which I suspect is a side effect of the varicella and measles vaccine.
Baby A has not shown any fever or rash symptoms yet, but I am concerned that they might develop them later.
Since everyone in the household is a confirmed case and still in isolation, I am a bit worried about any sudden changes.
Is there anything in particular that I should pay attention to?

A one-year-old infant is still very young, and their immune system is not fully developed.
It is important to be cautious of the warning signs of severe illness in the case of a COVID-19 infection (though it is emphasized that the likelihood of severe illness is extremely low, so there is no need to worry excessively).
If any of these warning signs of severe illness occur (please refer to the document), immediate medical attention should be sought.

When it comes to managing a post-vaccine COVID-19 diagnosis in children, especially in the context of your situation with two young children recently vaccinated and subsequently diagnosed with COVID-19, there are several important considerations for parents to keep in mind.
Firstly, it's essential to understand that while vaccines, such as the measles, mumps, and rubella (MMR) vaccine, are crucial for preventing serious diseases, they do not provide immediate immunity against COVID-19. Therefore, it is possible for vaccinated individuals to contract the virus shortly after vaccination, particularly if they were exposed to it before or shortly after receiving the vaccine. In your case, both children developed symptoms shortly after vaccination, which can be concerning for parents.
In your description, both children experienced fever and respiratory symptoms, which are common indicators of COVID-19. It is reassuring that your children are recovering, with a reduction in fever and ongoing management of cough and nasal symptoms. Here are some key points to consider as you navigate this situation:
1. Monitoring Symptoms: Continue to monitor both children for any changes in their symptoms. While mild symptoms like cough and nasal congestion can be managed at home, you should be vigilant for any signs of worsening condition, such as difficulty breathing, persistent high fever, or lethargy. If any of these symptoms occur, seek medical attention promptly.
2. Hydration and Rest: Ensure that both children stay well-hydrated and get plenty of rest. Hydration is particularly important in young children, as they can become dehydrated quickly, especially if they have a fever or are experiencing respiratory symptoms.
3. Managing Fever and Discomfort: Use appropriate fever-reducing medications, such as acetaminophen or ibuprofen, as recommended by your pediatrician. These can help manage fever and discomfort. However, always follow the dosing guidelines based on their age and weight.
4. Vaccination Side Effects: The rash that developed on B's body, neck, and face could indeed be a reaction to the MMR vaccine. Vaccine-related rashes can occur and are typically self-limiting. However, if the rash is extensive, accompanied by fever, or if you have any concerns, it’s best to consult with your pediatrician.
5. Isolation and Precautions: Since both children are confirmed COVID-19 cases, it is crucial to follow isolation guidelines to prevent spreading the virus to others. Ensure that they stay in a separate area of the home, if possible, and practice good hygiene, such as frequent handwashing and wearing masks if they are old enough.
6. Follow-Up Care: Keep in touch with your healthcare provider for follow-up care. They may recommend additional testing or monitoring, especially if symptoms persist or worsen.
7. Emotional Support: Lastly, consider the emotional well-being of your children during this time. Being sick can be stressful for young children, so providing comfort, reassurance, and distraction through play or reading can help alleviate their anxiety.
In summary, while the situation can be concerning, most children experience mild symptoms and recover well from COVID-19. By closely monitoring their health, managing symptoms effectively, and maintaining communication with your healthcare provider, you can help ensure a smooth recovery for both children. If you have any specific concerns or if their condition changes, do not hesitate to reach out to a medical professional for guidance.
