Washington (CNN) -- President Obama launched his health care reform effort shortly after taking office, saying the country could not afford to continue to sustain the costs and the burden on families.

The House is expected to vote soon on the health care bill that the Senate passed in December, though many House Democrats remain opposed to it.

One of the options for House Speaker Nancy Pelosi: having the House pass the Senate bill but following up with another vote in both chambers on a series of changes. The idea is to make the legislation more acceptable for House Democrats opposed to the Senate's version.

Although some of the provisions in the reform bill won't be implemented immediately, here's what Democrats say would go into effect in the first year after passage:

Eliminating caps: If you buy a policy, a health care company will not be able to place a lifetime -- or annual -- cap on how much they will cover. This is will be especially important for those diagnosed with serious illnesses, such as cancer, who face steep medical bills.

Pre-existing conditions: The Senate bill includes $5 billion in immediate support to provide temporary coverage to uninsured Americans with pre-existing conditions. The money would help you until the new health care exchanges in the Senate bill are put into effect in 2014.

Children and pre-existing conditions: Another thing that's going to be very important, CNN Senior Political Analyst Gloria Borger said, is that there will be no exclusion of children with pre-existing conditions.

Dependent children: Your children will be covered until the age of 26.

"Children who are over 21 and may not have a job that pays their health insurance can still be on your policy," Borger said. "That's very important to a lot of families."

Small business tax credits: Those tax credits are aimed at helping small businesses buy health insurance for their employees. Tax credits of up to 50 percent of premiums will be available to firms that offer coverage, according to the Senate's plan.

Preventive care: All new insurance plans, Obama said, will be required to offer free preventive care in order to "catch preventable illnesses and diseases on the front end."

Appeals process: A new independent appeals process will be set up for those who feel that they were unfairly denied a claim by their insurance company.

Help for seniors: If you fall into the Medicare Part D Drug Benefit coverage gap, dubbed the "donut hole," you will receive $250 to help pay for prescriptions.

Even with these changes, many activists in both parties are concerned about the specifics in the Democrats' bill.

"[The White House] says, 'These are the deliverable items [Democrats] can bring home to your constituents, and they're going to see it within the next six months,' and then the White House believes they're going to change their minds, and they're going to decide that they like health insurance reform," Borger said.
