Happy Winter! We now also have the updated Bivalent COVID booster from Pfizer-BioNtech and Moderna for ages 6 months to 4 years. You may call the front desk to book an appointment for one of our clinics. 

Children who received 2 doses of the primary series are elibigle to receive this booster 2+ months after the last dose of the primary series. 


We now have the updated Bivalent COVID boosters from Pfizer-BioNtech for ages 5-11. If you have an upcomming well visit- you may get your booster then, or:

Thursday evenings 6-7 in Weston (by appointment) 

Wed 9-5 in Medfield (by appointment) 


We are still able to offer both the Pfizer and Moderna COVID-19 primary vaccinations for our patients younger than 12- please call for appointments. 

If you have an appointment for a COVID vaccine, we can give your child a flu shot at the same time, however we can't give COVID vaccines at our flu clinics or nurse appointments.  Please contact the office if you have any questions. 


The updated (BIVALANT) COVID-19 boosters from Pfizer-BioNTech for people ages 12 years and older and from Moderna for people ages 18 years and older-has been approved.  Though all of our doctors highly recommend that eligible patients get these boosters, we don't have the staffing ability to be able to arrange Booster Vaccination clinics. For appointments at various pharmacies across the country, please go to: Updated COVID-19 boosters add Omicron BA.4 and BA.5 spike protein components to the current vaccine composition, giving more protection than previous vaccination by targeting these variants that are more transmissible and immune-evading. 
For more information about vaccination guidelines- we continue to use the CDC website as our resource.   

To summarize the current guidelines: 
Children ages 6 months through 4 years should get all COVID-19 primary series doses. 
Children ages 5 years and older should get all primary series doses, and the booster dose recommended for them by CDC, if eligible. 
Children ages 5 years to 11 years are currently recommended to get the original (monovalent) booster (THIS MAY CHANGE SOON- as  Pfizer and Moderna are seeking approval for the Bivalant booster for this age group).
People ages 12 years and older are recommended to receive one updated Pfizer or Moderna (bivalent) booster



It's that time of year again!  The doctors at PAW recommend that all children 6 months of age and up get their annual flu vaccine. 

Flu clinics at PAW begin the week of 9/19/22. If your child has an upcoming well visit- they may receive the flu vaccine at their visit.

A three-dose series (3ug each) is recommended with, 21 days between dose 1 and 2 and at least 8 weeks between dose 2 and 3.  

This vaccine may be given along with other vaccinations at an upcomming well visit, or separately through one of our scheduled clinics/ nurses visits. 

If you are interested in having your child vaccinated at PAW, please send a message on gateway through "request an appointment".  you will receive a call from our front staff to schedule. 

For more detailed information about the vaccine- please visit the or Website.

We hope to also be able to offer the Moderna vaccine in the near future (based on state allocation)- and will send a follow up message when that becomes available. 


By now, many of you have heard the news:

On June 18, 2022, ACIP voted unanimously to recommend the Moderna and Pfizer COVID-19 vaccines for young children. A short time later, CDC Director Rochelle Walensky endorsed the recommendation  as following: 

A two-dose Moderna COVID-19 vaccine series (25ug) is recommended for children ages 6 months – 5 years, under the EUA issued by FDA, 28 days apart.


A three-dose Pfizer-BioNTech COVID-19 vaccine series (3ug each) is recommended for children ages 6 month – 4 years, under the EUA issued by FDA, 21 days between dose 1 and 2 and at least 8 weeks between dose 2 and 3.

Your doctors at PAW are in the process of arranging clinics and preparing to give these vaccinations at well visits. We are hoping to vaccinate all of our interested patients ASAP. 

We will send out a blast via Gateway and have more details available on our website as soon as we can, 

Thank you for your patience,

Meanwhile- for more information about these vaccinations:

Today the office will be closing at 4PM as we say farewell to Dr. Andreea Cazacu. It has been a great 15 years and we are sad to see her go!

Dr. Andreea welcoming Dr. Abir in the Medfield office


We are having an outdoor gathering in the Medfield office parking lot for Dr. Cazacu's  patients on Wednesday, May 4 from 3-4:30 to bid her farewell. Dr. Abir Gerios-Azar (the new doctor that will be joining us in Medfield) will also be there to meet you all. 

If you can't make the gathering and you are interested in a more personal meeting with Dr.Gerios-Azar you may call the front desk to book a virtual appointment with her. 

Hope to see you all there!

Your team at Pediatric Associates of Wellesley. 


By now you should have received the news that Dr. Andreea Cazacu will be leaving Pediatric Associates of Wellesley in early May, 2022 to spend time with her aging parents. Of course, we are very sad to see her go and wish her all happiness. 

We are thrilled to welcome Dr. Abir Gerios-Azar, an experienced and kind physician, who will care for Dr. Cazacu's patients. We will have "open houses" in April so you can meet her before you may need her and you can make an appointment for a more intimate "meet and greet." If you already have an appointment with Dr. Cazacu scheduled after May 9, we will move that appointment to Dr. Gerios-Azar and call you to confirm this move.  If you would like to change your primary care provider to another doctor in our practice, please call our office and ask for Alyane Tilton, our Assistant Office Manager, who can assist with this. In our Medfield Office, Dr. Gerios-Azar and Dr. Raftery are accepting patients. In our Weston Office (for those who live in between), Drs. Curran, Landis, Yankelev and Zackin are accepting patients. She has been an important member of P.A.W.  and she will be greatly missed. We appreciate that our loss is small compared to yours as you lose a caring, thorough and thoughtful partner in the care of your children. Her difficult choice to seize these important years and care for her own family is characteristic of the kind and warm person that we have been privileged to work with these many years. 

Please know that we hope to continue to deliver the excellent care you have received from Dr. Cazacu. All of our doctors in both our offices are accepting patients, except Dr. Blumenthal whose practice is temporarily closed (as he becomes the Interim Chair of Pediatrics Department at Newton-Wellesley Hospital!). We are also thrilled to announce a new member of our team who will step into Dr. Cazacu's place in our Medfield office, Dr. Abir Gerios-Azar. 

Dr. Gerios-Azar was graduated from the American University of Beirut, Lebanon, and completed her medical education at its medical school. After completion of her pediatric residency there in 2001, she continued her education in the US and completed a second pediatric residency at SUNY and a pediatric gastroenterology fellowship at the Cleveland Clinic Foundation in Cleveland, OH (2004). Since then, she practiced primary care pediatrics in both the United States and Lebanon. Dr. Gerios-Azar is fluent in English, Arabic and French and when not caring for patients she enjoys nature, long walks, crafting and cooking. We are equally excited to welcome her husband and two school-aged children to our family.   

Dr. Abir Gerios Azar

We appreciate that change is hard and that Dr. Cazacu has been an important part of your family's life. We will work hard to fill that void and deliver the best pediatric care available. Plans for a celebration for Dr. Cazacu are underway and any letters or well-wishes can be sent to our Medfield office. 

With great thanks to Dr. Cazacu for her friendship, reliability and dedication and to you for your trust in us, 
The Staff and Doctors of Pediatric Associates of Wellesley
