Immunizations are one of the greatest success stories in public health. Thanks to vaccines, we’ve eradicated deadly diseases, saved millions of lives, and significantly reduced hospitalizations for conditions that once devastated communities. But with so much information (and misinformation) available today, many parents—and even adults—are left wondering: Are childhood vaccines safe? What vaccines are required for school? Where can I get an immunization shot?
As your primary care provider, I want to address those concerns head-on and provide you with a clear understanding of the importance of immunization, how to keep up with the vaccination schedule, and where to go when you or your child are due for a shot.
Why Are Vaccines Important?
Vaccines train your immune system to recognize and fight harmful infections—before you’re ever exposed to them. They help your body build immunity in a safe and controlled way, without causing the disease itself.
Why are vaccines safe?
Vaccines go through years of research, testing, and monitoring before they ever reach the public. They are studied in tens of thousands of people across diverse populations and are continuously monitored after approval. In fact, childhood vaccine safety is one of the most heavily researched areas of medicine.
Are childhood vaccines safe?
Yes. The current evidence overwhelmingly shows that childhood vaccines are both safe and effective. Serious side effects are extremely rare, and the benefits far outweigh any risks. Vaccine misinformation has unfortunately caused confusion and hesitation—but the scientific consensus is clear: vaccines save lives.
What Is the Standard Vaccination Schedule?
The vaccination schedule is a carefully timed plan developed by the CDC and the American Academy of Pediatrics. It tells us when to administer each vaccine to give children the best protection at the right ages.
What vaccines are required for school?
State laws vary, but generally the required school vaccines include:
- DTaP (diphtheria, tetanus, pertussis)
- MMR (measles, mumps, rubella)
- Polio
- Hepatitis B
- Varicella (chickenpox)
- COVID-19 (in some districts)
- Meningococcal and HPV (for middle and high school)
Schools will often ask for an immunization certification to prove that your child is up to date.
3-Year Check-Up Immunizations
At the 3-year check-up, many children have already received most of their primary vaccines. However, this visit is an important time to review the record and prepare for upcoming doses.
At this stage, we may:
- Confirm completion of primary series
- Update influenza (flu shot) annually
- Catch up on any missed immunizations
If you’re behind, don’t worry. There’s an immunization catch-up schedule designed to safely bring kids up to date without restarting the entire series.
What Is a Delayed Vaccine Schedule?
Some parents ask about using a delayed vaccine schedule—spreading out vaccines over a longer period instead of following the standard timeline.
Here’s what to know:
- The standard schedule is evidence-based and designed for optimal protection.
- Delaying vaccines can leave your child vulnerable to preventable diseases for longer than necessary.
- There is no medical benefit to delaying vaccines; it’s not safer.
If you’re concerned, talk openly with your provider—we’ll work with you to make sure your child stays protected while addressing your concerns with facts and compassion.
How to Memorize the Vaccine Schedule
The routine vaccine schedule can feel overwhelming—especially for new parents.
Here are a few tips:
- Use your pediatrician’s patient portal to track upcoming vaccines.
- Download a printable immunization chart from the CDC or your local health department.
- Set reminders in your calendar at key ages: 2 months, 4 months, 6 months, 12 months, 15 months, 18 months, 4–6 years, and 11–12 years.
- Keep a sample immunization record in your files (or digitally) and update it after every visit.
We’re happy to help you create a customized chart during your check-ups.
What Vaccines Do Adults Need?
Immunizations aren’t just for kids. Adults also need:
- Tetanus booster (Td or Tdap) every 10 years
- Annual flu shot
- COVID-19 vaccine and boosters
- Shingles vaccine (Shingrix) for adults 50+
- Pneumococcal vaccines for adults 65+ or with certain medical conditions
- HPV vaccine for adults up to age 45, depending on risk
- MMR or Varicella if not previously immunized
Ask during your next primary care visit if you’re unsure which vaccines you need.
Vaccine-Preventable Illnesses
Vaccines protect against dozens of potentially deadly or disabling illnesses, including:
- Measles
- Polio
- Hepatitis A & B
- Influenza
- Pneumonia
- COVID-19
- Meningitis
- Rotavirus
- Human papillomavirus (HPV)
- Tetanus and diphtheria
- Chickenpox
- Whooping cough
Many of these are vaccine-preventable illnesses that were once common but are now rare thanks to immunization efforts.
List of Diseases Eradicated by Vaccines
While not all diseases are eradicated, vaccines have helped eliminate or nearly eliminate several conditions in many countries:
- Smallpox – eradicated worldwide in 1980
- Polio – nearly eradicated globally
- Measles and rubella – eliminated in parts of the world (though outbreaks can still occur due to vaccine gaps)
These public health wins are only possible through widespread immunization.
Vaccine Misinformation: Sorting Fact from Fiction
Unfortunately, the rise of vaccine misinformation online has led some people to question the safety and necessity of immunizations. Common myths include:
- “Vaccines cause autism” – Debunked by multiple large-scale studies
- “Natural immunity is better” – Natural infection can be dangerous or fatal
- “Too many vaccines overwhelm the immune system” – The immune system is more than capable of handling multiple vaccines
If you’re unsure about something you’ve read, talk to your doctor—we’re here to provide accurate, science-based information.
Where to Get Immunization Shots
If you’re wondering “Where can I get an immunization shot?”, there are several options:
- Primary care offices – We provide all routine childhood and adult vaccinations.
- Public health departments – Often offer free or low-cost vaccines.
- Pharmacies – Many now offer flu, COVID-19, shingles, and other adult vaccines.
- School-based clinics – Often run immunization drives before school starts.
You can search for a vaccination center near me online or through your state’s health department.
If you’re a patient at our clinic, just call or book online—we’ll let you know what you need and when.
Immunization Certification and Records
When enrolling in school, daycare, college, or certain jobs, you’ll likely need an immunization certification or copy of your vaccine history.
Here’s how to get one:
- Ask your primary care provider or pediatrician
- Access your state’s Immunization Information System (IIS) if available
- Request a sample immunization record during your next visit
Pro tip: Snap a photo of your immunization record and store it in a secure folder on your phone for easy access.
Immunization Catch-Up Schedule
If you or your child has missed one or more vaccines, don’t panic. The CDC has a well-defined immunization catch-up schedule that outlines exactly how to safely resume vaccinations without repeating doses.
We can help you:
- Review what’s missing
- Develop a catch-up plan
- Ensure compliance for school or employment
Staying up to date protects you and your community.
Final Thoughts: Why Immunization Matters
Vaccines aren’t just about personal protection—they’re about community health. When more people are vaccinated, fewer people get sick. This protects the most vulnerable—infants, elderly adults, and people with immune disorders who can’t receive certain vaccines themselves.
To summarize:
- Immunizations are safe, effective, and life-saving
- The standard vaccination schedule provides the best protection
- Catch-up schedules are available if you’ve fallen behind
- Records and certifications are required for school, travel, and employment
- Vaccine-preventable illnesses are real—and still a threat without proper protection
