An unvaccinated couple died on the same day after catching Covid, leaving behind four heartbroken children.
Alvaro and Sylvia Fernandez, from California, US, passed away within hours of each other on December 19.
Mr Fernandez, 44, was worried about the vaccine and planned to carry out more research before getting the jab.
He and his wife, who was also unvaccinated, tested positive for Covid days before they died from complications caused by the virus, Mr Fernandez's sister Alma Hernandez said.
She added: "He (Alvaro) wanted to wait and do more research. He googled information. He didn't want to believe everything that was on the news.
"This is kind of an eye-opener for everybody in my family that whoever is not vaccinated definitely should have their vaccinations."
Mr Fernandez, who suffered from underlying health problems including diabetes, had been in a relationship with 42-year-old Sylvia since she was 15.
The pair met in high school, were married for 25 years and had four children including twins aged 17.
Alma said the high school sweethearts could not live without each other.
A GoFundMe page has been set up to support the couple's children - and it has already raised more than £15,000.
It comes after the grieving father of a "fit and healthy" young mum who suddenly died while 29 weeks pregnant said medics revealed she would still be alive if she "had taken the vaccine".
David Exley, 57, said his daughter Sadie, 24, had a “hunky-dory” pregnancy with no complications until she suddenly started suffering from migraines and chest pain.
But following tests at Pinderfields Hospital in Wakefield in October this year, the mum-of-two was diagnosed with a blood clot in her lung.
After catching Covid in late November, her condition deteriorated and a week later she was rushed to St James Hospital in Leeds when she became paralysed on one side, ExaminerLive reports.

She was transferred to Leeds General Infirmary and rushed to the intensive care unit where she was pronounced brain dead after suffering a brain haemorrhage on December 3.
Thankfully, doctors were able to save tiny Elliot who was delivered by emergency C-section at 29 weeks weighing just 2.1lbs.
Heartbroken David, from Birstall, said: “I got the news over the phone, it was just sheer panic. I drove straight to the hospital.
“I don’t know how to describe how I felt. My head was a shed.
“I didn’t eat for days, I was just waiting to know if she was going to be better.
“They tried to save her but it was apparent that we had lost Sadie.
“They saved baby Elliot but they couldn’t save our Sadie.”
