3. Why Do We Still Grow Flu Vaccines in Chicken
Eggs?
The majority of flu vaccines are grown in chicken eggs, a
method of vaccine development that’s been used
for 70 years.
One of the biggest problems has always been the supply of
suitable embryonated eggs, which have to be certified as safe for
making vaccines. You need to plan long in advance just to get
enough suitable eggs at the right time. It’s also time-consuming to
make vaccine this way, and hard to change once the
manufacturing process is started

4. Egg-Based Flu Vaccines
Egg-based vaccine manufacturing is used to make both inactivated
(killed) vaccine (usually called the “flu shot”) and live attenuated
(weakened) vaccine (usually called the “nasal spray flu vaccine”).
The egg-based production process begins with CDC or another laboratory partner in the WHO
Global Influenza Surveillance and Response System providing private sector manufacturers with
candidate vaccine viruses (CVVs) grown in eggs per current FDA regulatory requirements. These
CVVs are then injected into fertilized hen’s eggs and incubated for several days to allow the viruses
to replicate. The fluid containing virus is harvested from the eggs. For inactivated influenza vaccines
(i.e., flu shots), the vaccine viruses are then inactivated (killed), and the virus antigen is purified. The
manufacturing process continues with quality testing, filling and distribution.

antigens in their yolks for consumption
by humans and domesticated animals to
fight various diseases
