United States Vice President Kamala Harris, the Democratic presidential nominee, released a letter from her doctor that pronounced her in “excellent health” and fit for high office, in an effort to draw a contrast with her counterpart, Donald Trump.

In a memo released on Saturday, physician Joshua Simmons said Harris’s April exam was “unremarkable”, noting her active lifestyle, “very healthy diet”, seasonal allergies, sporadic hives, and moderate alcohol use.

“In summary, Vice President Harris remains in excellent health. She possesses the physical and mental resiliency required to successfully execute the duties of the presidency, to include those as chief executive, head of state and commander in chief,” Simmons wrote.

Harris, 59, is running against Republican Trump, 78, for the White House in November.

Locked in a tight race, Harris’s campaign hopes that contrasting her comparative youth and mental acuity with Trump’s more advanced age and tendency to meander, along with the differences in transparency between the two, will help convince undecided voters that she is more fit for office than he is.

Simmons said Harris’s allergies had been well-managed with over-the-counter and prescription medications.

Her urticaria, or hives, were “sporadic and transient and do not seem to be triggered by any particular exposure nor are they associated with other symptoms” and respond well to antihistamine treatment.

Harris has been on allergen immunotherapy for the last three years, dramatically improving her allergy and urticaria symptoms and negating her need for medication other than occasional nasal spray, he said.

Trump’s health

Former President Trump questioned President Joe Biden’s health when the 81-year-old president was seeking re-election. Since Biden was replaced on the ticket with Harris, Trump’s own health has drawn more attention.

According to a Harris aide, the vice president made her medical information public on Saturday in an effort to draw attention to Trump’s refusal to do so.

Trump has released very little health information, including after his ear was grazed by a bullet during an assassination attempt in July.

Last November, Trump marked Biden’s birthday by releasing a letter from his physician that reported the former president was in “excellent” physical and mental health.

The letter posted on Trump’s social media platform contained no details to support its claims – measures like weight, blood pressure and cholesterol levels, or the results of any test.
