Recommended Vaccines for Newborns

The Importance of Rotavirus Vaccine
The rotavirus vaccine, given in 2-3 doses before 6 months of age, shields against gastroenteritis, a common cause of gastrointestinal issues like diarrhea and vomiting in babies.
Protecting Against Chickenpox
The chickenpox (varicella) vaccine, provided after the first year of life, is advised in 2 doses for optimal protection.
Preventing Influenza Infections
Given the prevalence of influenza among children, the flu vaccine is highly recommended.
Immunization Schedule
It is important to follow the recommended immunization schedule for newborns to ensure they are protected against various diseases. Consult with your pediatrician to stay up to date with the latest vaccination recommendations.
Managing Post-Vaccination Reactions

It is common for babies to experience reactions following vaccinations. Here are some typical reactions and ways to address them.
Coping with Common Reactions
Reactions typically manifest within 24-48 hours and may include irritability and decreased appetite. Administering paracetamol can help alleviate fever.
Dealing with Swelling
Some babies may encounter swelling at the injection site, which can be eased with an ice pack. Paracetamol can also aid in pain relief.
The majority of post-vaccination reactions subside within 48 hours.
Exceptions are seen with live vaccines like MMR and chickenpox, where reactions may occur 4-10 days post-vaccination.
When to Seek Medical Attention
While most post-vaccination reactions do not necessitate a doctor’s visit, it is advisable to seek medical attention for high fevers or persistent crying. Consulting the administering doctor is recommended.

Addressing Post-Vaccination Symptoms
Many children experience minimal discomfort post-vaccination, with symptoms usually resolving within a few days. Severe side effects are rare.
Common Side Effects and Management Tips
- Learn about post-vaccination symptoms and how to manage them.
- Understand the rare and serious side effects of vaccines.
- Receive guidance on addressing concerns about your child’s reactions.
- It is common to experience mild side effects after vaccination, such as soreness at the injection site, fatigue, or mild fever. These symptoms usually go away on their own within a few days. To manage them, you can apply a cold compress to the injection site, rest, and stay hydrated.
- In rare cases, some individuals may experience more serious side effects, such as allergic reactions. If you or your child experience any concerning symptoms after vaccination, seek medical attention immediately.
- If you have any concerns about your child’s reactions to vaccines, don’t hesitate to reach out to your healthcare provider. They can provide guidance, address your concerns, and help you make informed decisions about vaccination.
Dealing with Typical Reactions
After vaccinations, common reactions include redness, loss of appetite, mild fever, irritability, and fatigue. The MMR and MMRV vaccines may lead to swelling and rashes.
If your child’s condition worsens, seek prompt medical advice.
Soothing Sore Spots
Post-vaccination sore spots can be comforted with a cool compress or cuddles.
Managing Reduced Appetite
Many babies and children may have a decreased appetite following vaccinations. It is important to monitor their fluid intake to prevent dehydration. Encourage your child to drink water, milk, or diluted fruit juices throughout the day. Offer small, frequent meals that are nutrient-dense to ensure they are getting adequate nutrition. Avoid forcing your child to eat if they are not hungry, as this can create negative associations with food. Be patient and understanding during this time, as their appetite should return to normal within a few days. If you are concerned about your child’s reduced appetite lasting longer than a week, consult their healthcare provider for further guidance.
Handling Mild Fevers
Mild fevers post-vaccination are common and typically resolve on their own. Dress your child in light clothing, provide fluids, and monitor their condition. Paracetamol or ibuprofen can help alleviate discomfort.
Comforting Your Child
Children may feel unsettled after vaccinations; offering comfort and hugs can help alleviate their distress.
It is important to reassure your child that they are safe and that the discomfort they are feeling is temporary. You can try distracting them with their favorite toy or book, or soothing them with gentle words and gestures. Physical touch, such as holding their hand or giving them a hug, can also provide comfort and help them feel secure.
Remember to praise your child for being brave during their vaccination and acknowledge their feelings. Let them know that it is normal to feel scared or upset, but that you are there to support them and help them feel better. By showing your love and support, you can help your child feel comforted and reassured during this challenging time.
Watching for Specific Reactions
Rotavirus vaccination may lead to vomiting and diarrhea in some instances. Monitor hydration levels and seek medical advice if symptoms persist.
Addressing Swelling

Parotitis, swelling of the salivary glands, can occur post-Mumps vaccination. It is noninfectious and typically resolves on its own.
To help reduce swelling and discomfort, you can try the following:
- Apply a warm compress to the affected area for 15-20 minutes several times a day.
- Drink plenty of fluids to stay hydrated and help flush out any toxins.
- Avoid sour or acidic foods that may irritate the salivary glands.
- If the swelling persists or is accompanied by fever, seek medical attention.
Remember to consult with a healthcare provider if you have any concerns or if the swelling does not improve. They can provide proper guidance and care for your specific situation.
Dealing with Rashes
A faint rash may appear after MMR or MMRV vaccinations, usually resolving without intervention.
Special Note on MMRV Vaccine
Children may develop red lumps and blisters near the injection site around five to 26 days after receiving the MMRV vaccine at 18 months of age. Typically, there are no more than five lumps or blisters.
Home Care Tips: The rash is not uncomfortable or contagious. No treatment is necessary.
Importance of Vaccination: Vaccinations effectively combat diseases and may cause a fever. This article addresses concerns regarding fever after vaccination and when to consult a primary care physician.
Understanding Vaccines: Vaccines enhance immunity against infectious diseases by using weakened or killed microbes. They prompt the immune system to produce antibodies, protecting against future infections.
Vaccine Safety: Vaccines rarely pose risks, and side effects such as fever, irritability, and redness typically subside quickly. In rare cases, symptoms like vomiting, diarrhea, joint, or muscle pain may occur.
Management of Fever After Vaccination: Fever boosts the immune response, and skipping medication is acceptable unless the child is uncomfortable. Rest, fluids, light clothing, and a humidifier can aid in alleviating symptoms. Consult a doctor if the child experiences extreme tiredness, pain, or difficulty swallowing fluids.
Seeking Medical Assistance: If your child experiences post-vaccination fever, set up an appointment with CareFirst 360 for primary care. Ensure your child receives all recommended vaccines for lifelong protection.
