Your calls about:

• A sore red arm two days after a second dose of shingles vaccine. Is this a local vaccine reaction or a secondary bacterial infection from the needle puncture?
• A woman mistakenly receives a two-hour expired dose of Pfizer vaccine when she was to have received a flu shot. We discuss her questions about receiving the flu shot immediately thereafter. There is no contraindication to receive a mRNA vaccine and flu shot despite the error. She may still have to get a third official dose of mRNA in the future depending on public health guidelines.
• A husband want to know how he can help his wife after she found out she had had a stroke. She had developed a headache and loss of balance.
• An explanation that 95% vaccine efficacy does not mean 95% of vaccinated people will not get sick and 5% will.
